Code snippets for writing files in Python, detailing methods and specifics of writing content to files, mainly including the write() method and writelines() method.
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.
