Code snippets for writing files in Python, detailing methods and specifics of writing content to files, mainly including the write() method and writelines() method.
#File Writing
Snippet Description
The open() Method
The open() method is used to open a file object. For specific usage, refer to Python read file example
The write() Method
Use the open() function to open a file, then use the write() method to write content to the file.
The writelines() Method
The writelines() method is used to write a list of strings to a file. However, note the following points:
- The writelines() method only accepts a list of strings as a parameter. If you want to write a single string, use the write() method.
- The writelines() method does not automatically add newlines between strings; you need to manually add them to the strings.
- The writelines() method does not add a blank line at the end of the list. If you need to add a blank line at the end, manually add an empty string containing a newline character.
- When using the writelines() method, ensure that the passed parameter is a list of strings. If the parameter is a generator object, convert it to a list before passing it.
