How can I print a list of letters separated by commas in a txt file without getting odd characters?

edit

You can use the following steps to print a list of letters separated by commas in a txt file without getting odd characters:

Step 1: Create a list of letters.

Step 2: Open a file in write mode.

Step 3: Use the "join" method to merge the list of letters with commas.

Step 4: Write the merged string to the text file.

Step 5: Close the file.

Here is an example code:

letters = ['a', 'b', 'c', 'd']
with open('letters.txt', mode='w') as file:
    string = ', '.join(letters)
    file.write(string)

This code will create a file named "letters.txt" and write the letters separated by commas "a, b, c, d" to the file without getting any odd characters.
