In this project we are going to learn how we can add text to an image.
This can be used
We will be using PIL (pillow) Library in this project
To create Image we will use Image and ImageDraw module
To set fonts we will use ImageFont module
and
To write text on an image we will use multiline_text() method if ImageDraw module
To Create an Image quote we require a background Image of our own choice on which we can write our quote
Lets define the tasks to be be performed for this project and work accordingly
Task 0: Import libraries:
from PIL import Image, ImageDraw, ImageFont
Task 1: Read an Image
imgObject=Image.open('full or relative path of your image')
Image.open() reads the image and returns an Image object
Task 2: Set the font of the text you want to add to the image
font_object = ImageFont.truetype("E:\\Font\\sunday-spring\\Sunday Spring.ttf", 350)
Download any font file of your own choice from google and specify the path inside truetype() method of ImageFont class
If you font file is with extension .otf then you can call opentype() method of ImageFont class
font_object = ImageFont.opentype("E:\\Font\\sunday-spring\\Sunday Spring.otf", 350)
Task 3 : Creating ImageDraw object to draw text on an Image
drawing_object = ImageDraw.Draw(imgObject)
Inside the ImageDraw.Draw we need to specify image object so that we can bind the drawing pen to the image
Task 4: Write the text
drawing_object.multiline_text((400,800), "MV's Code Guide", font=font_object, fill=(0, 0, 0))
With the drawing object call multiline_text() method to add multiline text or else you can call text() method to add single line text
Inside multiline_text() method :
ImageFont instance "left", "center" or "right". "rtl" (right to
left), "ltr" (left to right) or "ttb" (top to bottom).
Requires libraqm.Task 5: Save the new Image with text:
drawing_object.save('new_image.jpg')
Full code:
#Example: Create Image Quote from PIL import Image, ImageDraw, ImageFont # create an image object #imgObject = Image.new("RGB", (500, 500), (255, 255, 255))
imgObject=Image.open('Path of Image')
# get a font object
font_object = ImageFont.truetype("E:\\Font\\sunday-spring\\Sunday Spring.ttf", 350)
# get a drawing context
drawing_object = ImageDraw.Draw(imgObject)
# draw multiline text
drawing_object.multiline_text((400,800), "MV's Code Guide", font=font_object, fill=(0, 0, 0))
# save the image
drawing_object.save('new_image.jpg')
We are going to use pytesseract and pillow library to work on this project!
Before you start coding, you need to complete three tasks:
1. Click on the link below and install tesseract-OCR
https://github.com/UB-Mannheim/tesseract/wiki
After you install the setup successfully, take a note of where you are saving the file because we need that path in our code.
2. Install pytesseract by using command : pip install pytesseract
3. Install pillow by using command : pip install pillow
Source Code:
import pytesseract from PIL import Image pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe' value=Image.open('logo.png') text=pytesseract.image_to_string(value) print("Extracted Data is: \n ", text)
Notice that if you want to add full path, you need to add double slash (\\) instead of single slash (\) in you path
For Example: If your path looks like this: D:\Python_Program\my_Image.jpg
Then replace \ with \\
something like : D:\\Python_Program\\my_Image.jpg
Or
Add alphabet 'r' before your string
example: r'C:\Program Files\Tesseract-OCR\tesseract.exe'
and then you are good to go!
We can use two different packages to create spell checker
1. Using textblob
2. Using pyspellchecker
Video Explanation:
Source Code:
Using textblob:
from textblob import TextBlob misspelled_word= "Incorrct" corrected_word= TextBlob(misspelled_word).correct() print("Misspelled Word:",misspelled_word) print("Corrected Word: ",corrected_word) # you can also use list of misspelled words print("========================================================") misspelled_word_list=['Incorrct','Mang','Summay','Watr','Appl'] for word in misspelled_word_list: correct_word=TextBlob(word).correct() print("Misspelled Word:",misspelled_word_list) print("Corrected Word: ",correct_word)
Using pyspellchecker:
from spellchecker import SpellChecker spell=SpellChecker() misspelled_word=spell.unknown(['Incorrct', 'Summry','Mondy','Spellng','Pyhon']) print(type(misspelled_word)) for word in misspelled_word: print("Corrected word is ", spell.correction(word)) print("Candidate words:",spell.candidates(word))
You can play around this code and make changes according to your need!
You can also read a text file and use this code to check the spellings in the file
from textblob import TextBlob from spellchecker import SpellChecker f=open('demo.txt','r') data=str(f.read()) print(data) # you can also use list of misspelled words print("\n\n**************************Using textblob**************************************") misspelled_word_list= data.split() for word in misspelled_word_list: correct_word=TextBlob(word).correct() print("\nWord: ",word) print('------------------------------') print("Corrected Word: ",correct_word) print("\n================================") print('\n***************************Using pyspellchecker***********************************') spell=SpellChecker() misspelled_word=spell.unknown(misspelled_word_list) print(type(misspelled_word)) for word in misspelled_word: print("\nword: ",word) print('--------------------------------------------') print("Corrected word is ", spell.correction(word)) print('--------------------------------------------') print("Candidate words:",spell.candidates(word)) print("\n================================") f.close()
output:Artifcial intelligence (AI), someties called macine intelligence, is intellience demonstated by machines, unlike the
naural intelligence dislayed by humans and animls.

Without using count() method:

Without using count() method:
string_data=input("Enter string: ") d={} for x in string_data: d[x]=d.get(x,0) + 1 print(d) print(d.items()) # for meaningful output for key,value in sorted(d.items()): print(key,"occurred",value,"times")
Question by Subscriber:
How to ignore special characters like ? , . etc
If you want to ignore special characters and focus on the alphabets and digits only, then you can do that by some extra work
You can either import string class to get a set of all characters that you need to focus on, or you can manually add the set of characters you particularly want to focus on.
we will name them as valid_characters
Here goes the code:
import string string_data=input("Enter string: ") l=[] valid_characters=set(string.ascii_letters+string.digits) for x in string_data: if x in valid_characters: if x not in l: l.append(x) print(x,"occurred",string_data.count(x),"times")
Output: 
or
string_data=input("Enter string: ") l=[] valid_characters=set("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"+'0123456789') for x in string_data: if x in valid_characters: if x not in l: l.append(x) print(x,"occurred",string_data.count(x),"times")
Hope you like it ..!

Assume input string contains only alphabet symbols and digits.
We need to write a program to sort characters of the string were we will sort alphabets first and then digits will follow
Sample Input: C8N9A2U6R5B7
Output: ABCNRU256789
string_data=input("Enter some alphanumeric string to sort: ") alphabets=[] digits=[] for ch in string_data: if ch.isalpha(): alphabets.append(ch) else: digits.append(ch) result=''.join(sorted(alphabets)+sorted(digits)) print("You entered: ",string_data) print("Final result after Sorting: \n", result )
Sample string 1 : PYTHON

Let us understand the two scenarios of this problem
Scenario1: If both the strings are of same length:
string1=input("Enter first string: ") string2=input("Enter second string: ") i,j=0,0 # object initialization using Tuple Unpacking result="" while i<len(string1) or j<len(string2): result=result+string1[i]+string2[j] i=i+1 j=j+1 print("You entered first string : ",string1) print("You entered second string : ",string2) print("Final result after alternate merge: \n", result )
Scenario 2: If the strings have different length:
string1=input("Enter first string: ") string2=input("Enter second string: ") i,j=0,0 # object initialization using Tuple Unpacking result="" while i<len(string1) or j<len(string2): if i<len(string1): result=result+string1[i] i=i+1 if j<len(string2): result=result+string2[j] j=j+1 print("You entered first string: ",string1) print("You entered second string: ",string2) print("Final result after alternate merge: \n", result )

It returns reversed object and you can use join() method of strings to get your required output form reversed object.
