This is the code:
def is_prime(p):
for i in range(2, p):
if p % i == 0:
break
else:
print("Prime")
def main():
p = int(input())
is_prime(p)
main()
My question is, why the 'else statement' works if it's on another indentation level than the 'if'?, my guess is that because the 'for loop' is on the same indentation level that the 'else' is, the 'break statement' make the 'else' attached to the 'if', but i don't know.
The code is using a for-else clause, not an if-else clause!
for blah:
do stuff
else:
do more
The do more clause is executed if and only if you exit the for loop normally, i.e. without raising an error or using a break statement.
From the documentation: "The break statement, like in C, breaks out of the innermost enclosing for or while loop.
Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the iterable (with for) or when the condition becomes false (with while), but not when the loop is terminated by a break statement."
