# Textfiles b – Python Program to Generate 26 Text Files named A.txt, B.txt, and so on up to Z.txt

Files In Python:

Textfiles b: A file is a piece of data or information stored on a computer’s hard drive. You’re already familiar with a variety of file kinds, including music, video, and text files. Manipulation of these files is trivial with Python. Text files and binary files are the two types of files that are commonly used. Binary files contain binary data that can only be read by a computer, whereas text files include plain text.

For programmers and automation testers, Python file handling (also known as File I/O) is a crucial topic. Working with files is required in order to write to or read data from them.

In addition, if you didn’t know, I/O activities are the most expensive techniques via which software might fail. As a result, when implementing file processing for reporting or any other reason, you should proceed with caution. The construction of a high-performance application or a robust solution for automated software testing can benefit from optimizing a single file activity.

The task is to generate 26 Text Files with names A.txt, B.txt, and so on in Python. Open Txt Files In Python, Python Write Txt, Python Read Txt File.

## Program to Generate 26 Text Files named A.txt, B.txt, and so on up to Z.txt in Python

Logic:

Here we iterate from 65(Ascii value of ‘A’) to 65+26 and convert this ASCII value to the character using chr() function.

We make the new files using the write function.

Write function creates the file if the file doesn’t exist.

Approach:

• Here we iterate from 65(Ascii value of ‘A’) to 65+26(Z) using For loop. So Z.
• Convert this ASCII value to the character using chr() function and store it as the filename.
• Open this file in writing mode by passing the first argument as filename and the second argument mode as w(Writing mode).
• Write some dummy data to file using the writelines() function.
• Here we write the character value to file.
• The Exit of the Program.

Below is the Implementation:

# 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 and store it as filename
filename = chr(i)+'.txt'
# Open this file in writing mode by passing the first argument as filename and second argument mode as w(Writing mode)
with open(chr(i) + ".txt", "w") as file:
# Write some dummy data to file using the writelines() function
# Here we write the character value to file
file.writelines(chr(i))


Output:

Explanation:

• The file path is stored in the variable ‘file name.’ Change the value of this variable to the path of your own file.
• Dragging and dropping a file onto the terminal will show its path. The code will not run unless you change the value of this variable.
• The file will be opened in reading mode. Use the open() function to open a file. The path to the file is the method’s first parameter, and the mode to open the file is the method’s second parameter.
• When we open the file, we use the character ‘w’ to signify write-mode.
• Here we get all the filenames using the ASCII values(Converting them to characters).
• Here write mode creates the file with the above filename.
