List of alphabets python – Python Program to List English Alphabets in a File by Specified Number of Letters on Each Line

• Give the number of characters in a line as static input and store it in a variable.
• Take an empty string to store all the alphabets in the English language(Capital letters).
• Here we iterate from 65(Ascii value of ‘A’) to 65+26(Z) using For loop.
• Convert this ASCII value to the character using chr() function.
• Add this character to the alphabets string using the string concatenation.
• Make a single variable to store the path of the file. This is a constant value
• This value must be replaced with the file path from your own system in the example below.
• Open the file in write-only mode. In this case, we’re simply writing the contents of the file.
• Use list comprehension, For loop and slicing to make numblines number of characters in each line.
• Here we added (‘\n’) to separate the lines.
• Write the above-modified letters to the file using the writelines function.
• The Exit of the Program.

Below is the implementation:

# Give the number of characters in a line as static input and store it in a variable
numblines = 5
# Take a empty string to store all the alphabets in English language(Capital letters)
alphabets = ""
# Here we iterate from 65(Ascii value of 'A') to 65+26(Z) using For loop
for i in range(65, 65+26):
    # convert this ASCII value to the character using chr() function
    charvalue = chr(i)
    # add this character to alphabets string using the string concatenation
    alphabets += charvalue
# Make a single variable to store the path of the file. This is a constant value
# This value must be replaced with the file path from your own system in the example below.
filename = 'samplefile.txt'
# Open the file in write-only mode. In this case, we’re simply writingthe contents to the file.
with open(filename, "w") as file:
    # Use list comprehension,For loop and slicing to make numblines number of characters in each line
    # Here we added ('\n') to separate the lines
    modifiedletters = [alphabets[i:i + numblines] +
                       "\n" for i in range(0, len(alphabets), numblines)]
    # write the above modified letters to the file using the writelines function
    file.writelines(modifiedletters)

Output:

ABCDE
FGHIJ
KLMNO
PQRST
UVWXY
Z

# Give the number of characters in a line as user input using the int(input()) function and store it in a variable.
numblines = int(input('Enter the number of characters in a line you want : '))
# Take a empty string to store all the alphabets in English language(Capital letters)
alphabets = ""
# Here we iterate from 65(Ascii value of 'A') to 65+26(Z) using For loop
for i in range(65, 65+26):

    # write the above modified letters to the file using the writelines function
    file.writelines(modifiedletters)

Output:

Enter the number of characters in a line you want : 7
