A for loop iterates through an iterable, may that be an array, a string, or a range of numbers
#Example:
myArr = ["string 1", "string 2"]

print(x)
#Returns "string 1", "string 2". In here the x is an iterator and does not need to be defined.
# Python for loop

print(i) # prints the number of i (equals to the loop number)
for x in [1, 2, 3, 4, 5]:
# it will loop the length of the list (in that case 5 times)

# For loop where the index and value are needed for some operation
# Standard for loop to get index and value
