Reverse-Replace Python function

Question

Hi, I need an inverse to replace function in Python.
This is the example:

a = 'Whisky in a jar'

#If I use the normal regular way (not-inverse one)

a.replace('a', '_')

a = 'Whisky in _ j_r'

#But I need the exact opposite. I need it to return like this:

a = '______ __ a _a_'

What code should I use?

Answer 2

Replace works like this:
res = ""
for i in a:
if i=="whatever I need":
res+='replacement'
else:
res+=i

That's how replace works. So if you want to EXCLUDE those words, then replace the equality with an inequality, aka

if i!="whatever I need"

# I got solution try this:

a = "Whiskey in a kar"
for i in a:
if i!='a':
a=a.replace(i,'_')
print(a)

#To run this simply paste it to python console

# Hope this helps😄

Esteban Perez-Ortiz Thank you. Actually, if you want to use the syntax a.inverse_replace(x, y) instead of inverse_replace(string, x, y), you have to make it a class:
