How do I reverse each word in a string, but in the same sentence order? [duplicate]

Reverse each word in a string (7 answers)

Closed 3 years ago.

I tried doing this

while 1:
    line = input('Line: ')
    print(line[::-1])

but all that did was reverse the whole sentence, I was wondering if someone could help me with a program that converts 'hello world' to 'olleh dlrow' instead of 'dlrow olleh', and how do I make a loop that stops when the input is nothing, or just a space? Thank you in advanced!

回答1:

You need to split the sentence, reverse the words, then reassemble.

The simplest way to split is to do so on whitespace, with str.split(); reassembly is then just a case of re-joining the reversed words with a space:

' '.join([word[::-1] for word in line.split()])

Demo:

>>> line = 'hello world'
>>> ' '.join([word[::-1] for word in line.split()])
'olleh dlrow'
