indentation levels in programming
value = 18
typer = "integer"
if value > 20:
print("It's greater than 20")
if typer == "integer":
print("Oh number")
else:
print("Oh no number")
#the fisrt if is on indentation level zero,print inside it is on indentation level 1 and so on
#in some programming languages first level starts as one rather than zero
