Definition:
A "for loop" is something used for repeating things over a list of items. For instance, a list or a dictionary.
Code:
colors = ["red", "green", "blue"]
for x in colors:
print(x)

Real-Life Example:
A real-life example would if I was a manager or boss for a company say that everyone was off a certain day. Like, if I said everyone was off for Christmas the 25th. If I had 1000 employees that would take a very long time to send an email to everyone. Instead of sending an email to everyone I can program code that uses "for loops" and "while loops" to create a message and send it to everyone.
