Python While Loops

print_str = "Water falls"

# TODO: initialize a counting variable "i" to 0 - you'll use this to track which character of the string you're on
i = 0
# TODO: write your while header line, comparing "i" to the length of the string
while i < len(print_str):
 print(print_str[i])
 i += 1
 # TODO: here in the body of the loop, print out the current character from the string
 
 # TODO: increment your counter variable in the body of the loop, so you don't loop forever!
