Why this code shows no output?

Question

def happy(m):
b=m
z=m
c=0
while(z>9):
while(b>9):
c=((b%10)**2)+c
b=b/10
z=c
while(c==1):
return "h"
return "nh"
a=19
print(happy(a))

Answer 1

I think, check that your loop is inifinite.
z>9 is always true because c is keeps on increseing. And so z by z =c So you have infinte loop..
Note:
b/10 floating division => 1.9
b//10 integer division => 1

Answer 2

Why so many while loop?

What you want to do?

Answer 3

Gani Ganesh

b = 19
z = 19

while 19 > 9: #true
while 19 > 9: #true
c = (19 % 10) ** 2 + 0 = 81
b = 19 / 10 = 1.9
z = 81

Now z became 81 and b became 1.9

So while 81 > 9:
This would be always True means Infinite loop

So while c == 1: would be never work.

That is why there is No output because of Stack overflow
