File Modes with open()
The open() function returns a file object. The second argument is the mode: "r" (read), "w" (write, overwrites), "a" (append), "x" (exclusive creation). Always close files when done.
f = open("example.txt", "w")
f.write("Hello, file!")
f.close()
f = open("example.txt", "r")
content = f.read()
f.close()
print(content)The with Statement
The with statement automatically closes the file, even if an error occurs. It's the safest and most readable way to work with files.
with open("example.txt", "w") as f:
f.write("No need to close manually!")
with open("example.txt", "r") as f:
print(f.read())
