Python: Read Entire File at Once

In Python, you can use the read() method to read the entire contents of a file at once. Below is an example code that reads the contents of a file and prints it.

with open('example.txt', 'r') as file:
    content = file.read()
    print(content)

In the example above, the file “example.txt” is first opened using the open() function with the mode set to ‘r’ (read-only mode). The content of the entire file is then read using the read() method and stored in the variable content, which is then printed. After reading the file, it is important to remember to close it. This can be done automatically using the with statement.
