re.sub(r'a(?=b)','*','The lion and the Fox')

Question

I need to get the inputs and then substitute with * but Im not getting output , like if I give,
a=input()
b=input()
c=input ()
print(re.sub(r'a(?=b)','*',c))
Instead of the input string, the characters a and b are replaced in 'c'. How to replace the given string with the INPUTS a and b ??

Answer 1

Valmob101 a=aa b=bb c= my string is aa bb , output:: my string is * bb

Answer 2

use:( f ".........." ) instead of r , then place variables inside {}.

e.g. f "hello{a}"

Answer 3

Mndm r stands for raw string which means the string cannot escape character by \(backslash)

f stands for format in which we can include identifiers, vars etc. Inside{}. It is a replacement for .format.

Answer 4

Valmob101 sorry but I didn't get the output

Answer 5

Mndm Please also include the output you want.

Answer 6

Mndm solution to yours:
Use this pattern instead:
re.sub(f'{a} (?={b})','* ',c)

To fulfil your output you should include *space* after {a} and *
