Here’s the basic syntax:

file = open("filename.txt", "mode")

Common File Modes

Mode Meaning Description
'r' Read Opens file for reading (default). Error if file doesn’t exist.
'w' Write Opens file for writing. Creates new or overwrites existing file.
'a' Append Opens file for appending. Adds data to the end.
'x' Create Creates new file. Error if file exists.
'b' Binary Used with binary files (e.g., 'rb', 'wb').
't' Text Used with text files (default mode).
'+' Read & Write Allows reading and writing (e.g., 'r+', 'w+').

Example 1: Read a file

file = open("example.txt", "r")
content = file.read()
print(content)
file.close()

Example 2: Using with (Best Practice)

Automatically closes the file after use:

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

Example 3: Write to a file

with open("example.txt", "w") as file:
    file.write("Hello, World!")

Example 4: Append to a file

with open("example.txt", "a") as file:
    file.write("\nThis line is added at the end.")

Example 5: Read line by line

with open("example.txt", "r") as file:
    for line in file:
        print(line.strip())
