Python create and write to file

  • by

Use the file Open() function with the “w” letter in our argument to create and write to file in Python. “w” indicates Python write to file and it will create a file in Python if it does not exist in the library.

f = open(path_to_file, mode)
f = open("test.txt","w+")

'w' – open a file for writing. If the file doesn’t exist, the open() function creates a new file. Otherwise, it’ll overwrite the contents of the existing file.

'x' – open a file for exclusive creation. If the file exists, the open() function raises an error (FileExistsError). Otherwise, it’ll create the text file.

Simple example code.

for i in range(5):
    f.write("This is line %d \n" % (i + 1))



Python create and write to file

Another example, the following creates a new file called readme.txt and write some text into it:

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')

Using the try-except statement

    with open('docs/readme.txt', 'w') as f:
        f.write('Create a new text file!')
except FileNotFoundError:
    print("The 'docs' directory does not exist")
