Python – Write String to Text File
Now you can save or write string to text a file in persistent data storage using Python.
To write string to a Text File, follow these sequence of steps:
- Open file in write mode using open() function.
- Write string to the file using write() method.
- Close the file using close() method.
Example 1: Write String to Text File
In the following example, we will take a string constant and write the string to a text file by following the above said sequence of steps.
text_file = open("sample.txt", "w") n = text_file.write('Welcome to pythonexamples.org') text_file.close()
The write() method returns the number of characters written to the text file.
Note that this kind of writing to text file, overwrites the data, if the file is already present. If the file is not present, it creates a new file and then writes the string to the file.
Example 2: Write String to Text File in Text Mode
A file can be opened in two modes: the first one is text mode and the second one is binary mode. By default a file is opened in text mode. However, you can explicitly specify the mode.
In the following example, we will open the file in text mode by appending “t” to the mode and write the string to a text file by following the sequence of steps mentioned at the start of this tutorial.
text_file = open("sample.txt", "wt") n = text_file.write('Welcome to pythonexamples.org') text_file.close()
Writing other than String to Text File
If you would like to write any Python object other than string or a bytes object to a file, using write() method, you should first convert that Python object to a string or bytes object.
In this tutorial of Python Examples, we learned how to write a string to a text file, with the help of example programs.
