Question

str1=str(input())
str2=str1.lower()
h=str2.split()
k=0
for a in h:
for i in a:
j=ord(i)
k=j-96
c=a.count(i)
a.replace(i,chr(122-k),c)
u=''.join(a)
print(u)

Answer 1

.replace() does not occur in place, it returns a value so should be used like a = a.replace()
Your .join() statement will not work correctly
