Working with Files

file = open("data.txt", "r")
content = file.read()  # Read all
file.close()

file = open("data.txt", "r")
for line in file:
    print(line.strip())
file.close()

file = open("output.txt", "w")
file.write("Hello, World!")
file.close()

file = open("log.txt", "a")
file.write("New entry\n")
file.close()

With Statement (Best Practice)
with open("data.txt", "r") as file:
    content = file.read()
# File auto closes

# Save scores
with open("scores.txt", "w") as file:
    for name, score in scores.items():
        file.write(f"{name}: {score}\n")

# Read scores
with open("scores.txt", "r") as file:
    for line in file:
        name, score = line.strip().split(":")
        print(f"{name} scored {score}")
