Using another variable

str1 = ''

for i in range(len(list1)):
#print (list1 [i])
if list1[i] == ' ' and list1[i - 1] != ' ':
str1 += list1[i]
elif list1[i] != ' ':
str1 += list1[i]

print(str1)

You can remove within a range at once but on different indexes I don't think we can do at once

Answer 6

The most efficient way to do it is probably regex pattern substitution.

Answer 7

One liner:

Edit: I see the problem has been changed to not allow split() as well (previously just didn't allow join). So this solution no longer qualifies

Answer 8

Steve
Python magic.😎Thumbs up.

I was going for

print((' '). join(sentence.split()))

but your

print(*sentence.split())

was just better.

Strings are immutable. What you're trying to do cannot be done like this.
