loops in python

LOOPS:

Code can be repeated using a loop. Lines of code can be repeated N times, where N is manually configurable. In practice, it means code will be repeated until a condition is met.

Python has 3 types of loops: while loops , nested loops and for loops.

For loop

We can iterate a list using a for loop

member= [ "Abby","Brenda,"Clindy","Diddy" ]   for i in member: print(i)

The for loop can be used to repeat N times too:

for a in range(1,10):

  print(a)

WHILE LOOP :

If you are unsure how many times a code should be repeated, use a while loop.
For example,

correctNumber = 5
guess = 0

while guess != correctNumber:
    guess = int(input("Guess the number: "))

    if guess != correctNumber:
        print('False guess')

print('You guessed the correct number')

We can combine for loops using nesting. If we want to iterate over an (x,y) field we could use:
for example:

for x in range(1,10): for y in range(1,10): print("(" + str(x) + "," + str(y) + ")")

Nesting is very useful, but it increases complexity the deeper you nest
