for i in [7, 12, 3]:    statementsprint(i)    # Output 3 

Alternatively, loops can be formulated using while. The indented statements are then executed as long as the condition is met.

while condition:    statements

for var in elements:    statement1    if condition: break       # abort the loop    statement2 

continue skips the remaining statements for the current loop pass but then ...
