python 2.7 for loop repeat iteration

Question

first, I'd like to say I'm sorry because my english is not good enough but hopefully you'll understand me. I searched internet and couldn't find how to do this in python 2.7, I know it could be done with while loop but I'd like to know if it is possible to be done with for, also.

if we have a for loop that looks like this

for counter in range(0,len(list)):
    if (condition):
        var=something from dictionary

and i need to repeat the same iteration of loop if this condition is true. Tried with i=i-1 but that didn't work and I later found out that python creates a list of numbers on the beginning of a loop, tried xrange also but didn't work. So, does anyone know how to do this?

Put a while condition inside the for loop?

What you need here is a while loop. It will be much easier for you to control the iterations inside the loop. You can structure it like this:

i = 0
while i < len(list):
    if condition:
        var = something from dictionary
    else:
        i++

Did it like this actually, but in c could use for and repeating iteretions so wanted to know if this could be done in python too

Read this from the python docs on the difference between the for loop in python and its C counterpart. docs.python.org/2/tutorial/controlflow.html

have you tried

for l in list:
    if(condition):
        var=getValue()

for more examples details you will probably find a good examples at Python ForLoop
