Changing step in Python loop

You could do it with a while loop:

step = 1
i = 1
while i < 100:
    if ...... :
        step = 1
        #do stuff
    else:
        step = 2
        #do other stuff
    i+=step

you would need to increment step manually which can be done using a while loop. checkout difference between while and for loop.

The for statement iterates through a collection or iterable object or generator function.

The while statement simply loops until a condition is False.

if you use a while loop your code would look something like this:

step = 1
i = 1
while i < 100:
    if ...... :
        step = 1
        #do stuff
    else:
        step = 2
        #do other stuff
    i = i + step

np.arrange creates a (numpy) array with increasing values. The for-loop goes through all the values of the array. (Numpy is a powerful library for computations with numerical arrays)

import numpy as np
for i in np.arange(start,stop,stepwidth):
    # your stuff
