read file in python

To read a file in Python, you can use the built-in open() function. The syntax for opening a file is:

main.py
file_object = open('filename', 'mode')
39 chars
2 lines

where filename is the name of the file you want to open, and mode is the mode in which you want to open the file (i.e., read, write, append, etc.).

To read the content of the file, you can use various methods available for the file object. One of the most common methods is read() which will read the entire content of the file at once. Here is an example code that reads a file:

main.py
with open('example.txt', 'r') as file:
    content = file.read()
    print(content)
84 chars
4 lines

In this example, the code opens the file named example.txt in read mode ('r') using the with statement. The with statement is used because it automatically closes the file when the block is exited. Then, the read() method is used to read the entire content of the file into a variable called content. Finally, the content of the file is printed to the console.

There are many other methods available for reading files in Python, such as readline(), readlines(), seek(), and more.
