FOR loops

301.10 Iteration

Iteration — Note 1 of 4

Repeat N times.

A for loop repeats a block a fixed number of times. Use range() to generate the sequence of values for the loop variable.

FOR loop with range

python

for i in range(5):
    print(i)      # 0 1 2 3 4

for i in range(1, 4):
    print(i * 2)  # 2 4 6
