You must count each character, including spaces and punctuation, So even if the string has spaces like“hello world”, the number of characters would be 11 because there’s a space between the two words. Python provides a built-inlen()function that returns the number of characters(including ...
In the output, we see that the method returns a copy of the string with the first two occurrences of house replaced by car. Interactive Example In the below example, you will: Find if the substring actor occurs between the characters with index 37 and 41 inclusive. If it is not detected...
Here, we are going to implement a python program in which we have to compare the strings and find the matched characters with given string and user entered string.
