What is wrong in this??? This is the code for conversion of upper to lower and vice versa without using inbuilt function

Question

str=input()
char=input()
for i in range(len(str)):
if (char>64) and (char<91):
char=char+32
print(char)

elif (char>96) and (char<123):
char=char-32
print(char)

if char==32:
print(" ")

print(str)

Answer 1

Disha Jain ,

there are several issues in the code:

▪︎you are using variable 'char' for comparing against upper or lower, this is not correct
▪︎in the for loop you get the individual characters of the string in the variable 'i'.
▪︎use 'i' after converting it to the ascii value by using ord() for the comparison
=> so the code has to be reworked

happy coding and good success!

Answer 3

chr() and ord() are inbuilt functions. I don't think you can do it without them.

Answer 4

my code is close to the ones of JaScript, but it handles and keeps characters like punctuation:
