Loops
Python has two loop types: for (used to iterate over a sequence like a list, string, or range of numbers) and while (repeats while a condition is true). Python's for loop is fundamentally different from C/Java's — it always iterates over an iterable, not a counter.
💡 Key insight
Python has no do-while loop — use a while True loop with a break condition to get the same effect.
Syntax
syntax
for item in iterable:
# code
while condition:
# codeExample
range(1, 6) generates the numbers 1 through 5 (the end value is excluded).
py
for i in range(1, 6):
print(i, end=" ")output1 2 3 4 5
