Python supports file handling and allows users to handle files i.e., to read and write files, along with many other file handling options, to operate on files. The concept of file handling has stretched over various other languages, but the implementation is either complicated or lengthy, like other concepts of Python, this concept here is also eas...
Before performing any operation on the file like reading or writing, first, we have to open that file. For this, we should use Python’s inbuilt function open() but at the time of opening, we have to specify the mode, which represents the purpose of the opening file. Where the following mode is supported: 1. r: open an existing file for a read opera...
There is more than one way to How to read from a file in Python . Let us see how we can read the content of a file in read mode. Example 1: The open command will open the Python file in the read mode and the for loop will print each line present in the file. Output: Example 2: In this example, we will extract a string that contains all characters i...
