doesn`t work with regular and reverse words
In a given string you should reverse every word, but the words should stay in their places. Input: A string. Output: A string. Precondition: The line consists only from alphabetical symbols and spaces.
I tried this one:
text: ('Hello world') #with many spaces between words li2: ['Hello', 'world'] li: ['olleH', 'dlrow']
and then replace in original text:
text = text.replace(li2[i],li[i])
def backward_string_by_word(text: str) -> str: li =  li2 = text.split() #revers all words for a in text.split(): li.append(a[::-1]) #word replacement in text for i in range(0,len(li2)): text = text.replace(li2[i],li[i]) return text
This code works in all asserts:
assert backward_string_by_word('') == '' assert backward_string_by_word('world') == 'dlrow' assert backward_string_by_word('hello world') == 'olleh dlrow' assert backward_string_by_word('hello world') == 'olleh dlrow' assert backward_string_by_word('welcome to a game') == 'emoclew ot a emag'
But code does not work if string has a regular word and its reverse:
(backward_string_by_word('iH Hi')) == 'iH iH' (backward_string_by_word('Hello olleH')) == 'Hello Hello' (backward_string_by_word('Hello 2olleH')) == 'olleH Hello2' (backward_string_by_word('Hello olleH hi ih yes s2ey code')) =='Hello Hello hi hi sey ye2s edoc'
What do I need to know to understand the cause of the problem or what am I doing wrong?
The question is resolved.
