for and while Loops in Python - DJC
Loops allow you to repeat a block of code multiple times.
for: iteration over collections
It is used to iterate through elements of a sequence (list, tuple, string, etc.).
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(fruit)
It can also be used with the range() function:
for i in range(5):
print(i) # Prints from 0 to 4
while: repetition while a condition is true
The while loop runs as long as the condition is true.
counter = 0
while counter < 5:
print("Counter:", counter)
counter += 1
Caution:
A poorly defined while loop can cause infinite loops if the condition never becomes false.
