Why only p is printing? Loop is working only for one time why?

Question

#to print
'''p
py
pyt
pyth'''

s="phyton"
j=0
for i in range (0,j+1):
print(s[i],end=" ")
j=j+1

Answer 1

The range function returns an iterator object which basically the for loop uses to get values from. This object is only created once in a loop causing your problem. To fix this I would change the loop to:

for i in range(len(s) + 1):
print(s[:i])

It takes the length of the string to get the indexes and uses array slicing to grab the section of the string from index 0 to i.

Answer 2

But j value is increasing every time

Answer 3

Are you trying to simulate a while loop there?

Python range() accepts an integer and returns a range object, which is nothing but a sequence of integers. You can’t increment j after!

Answer 4

range(0, j+1)
where j=0 that means range(0,1) thats why its only executed once
