Writing Files

PY · File I/O

syntax

with open(path, 'w') as f:
    f.write(text)

example

lines = ["alice,95", "bob,82", "carol,91"]

with open("scores.csv", "w", encoding="utf-8") as f:
    f.write("name,score\n")
    for line in lines:
        f.write(line + "\n")

# Append mode
with open("scores.csv", "a") as f:
    f.write("dave,88\n")

Note 'w' mode truncates the file first. Use 'a' to append. Use 'x' to create exclusively (fails if file exists).
