nt = txt.replace("b", "")
print(nt)

one()

why this dont replace everything?

Answer 1

If you are trying to replace a and b, try this
txt= "xaby"
def one ():
n = txt.replace("a","")
b = n.replace ("b","")
print (n)
print (b)
one()

Answer 2

For fun, try this

user_txt = input()

def remove_lc_letters(txt):
"""Sequentially remove lower case letters."""
for i in range(97, 123):
txt = txt.replace(chr(i), "")
print(txt)

remove_lc_letters(user_txt)

Answer 3

David Ashton ur code is good
But when i
input :abcd..

Output:

abcd
bcd
cd
d
# all fine upto thz...

But in this case
input: fun

Output:

Fun

Fun
Fun
Fun
un
un
un
un
n
n

n..

Also in code y u used range(97,123)...

Here's version 2.0: only prints if letter removed

user_txt = input()

def remove_lc_letters(txt):
"""Sequentially remove lower case letters."""
for i in range(97, 123):
if chr(i) in txt:
txt = txt.replace(chr(i), "")
print(txt)

remove_lc_letters(user_txt)

what is your expected output

Answer 8

OK Here's version 3.0 - replaces upper and lower case letters and spaces.

user_txt = input() or "Hello World!"

def remove_lc_letters(txt):
"""Sequentially remove upper and lower case
letters and spaces.
"""
for i in range(65, 91):
if chr(i) in txt:
txt = txt.replace(chr(i), "")
print(txt)
if chr(i + 32) in txt:
txt = txt.replace(chr(i + 32), "")
print(txt)
if " " in txt:
txt = txt.replace(" ", "")
print(txt)

remove_lc_letters(user_txt)

Reminds me of this silly code

Answer 10

damn sorry
the right code is this:
def one():
nt = txt.replace("a", "1")
nt = txt.replace("b", "2")
print(nt)

one()

when i input ab or whatever it only replaces b, why dont replace a to?
