File IO (Writing)

1. File open in write mode ("w")

file = open("example.txt", "w")  # "w" = write mode
file.write("Hello AIkiPadhai!\n")
file.close()

2. File open in append mode ("a")

file = open("example.txt", "a")  # "a" = append mode
file.write("This is new line.\n")
file.close()

3. Writing multiple lines

lines = ["Line 1\n", "Line 2\n", "Line 3\n"]
with open("example.txt", "w") as file:
    file.writelines(lines)

4. Using with statement (recommended)

with open("example.txt", "a") as file:
    file.write("Appended using with statement.\n")
