I feel like my check_string() function isn't very pretty. What's the preferred syntax for folding a list of class methods into a list comprehension? I found a possibly relevant Stack Overflow question but couldn't quite make heads or tails of it. It just doesn't seem right to...
In this problem, we are given a string, and we need to find the length of the longest substring without repeating characters. For example, the input string is “abcabcbb”. The answer is “abc”, with the length of 3. If the input string is “bbbbbb”, the answer is “b”, wi...
Also please include simple test function to test the class methods. Hints: Use init method to construct some parameters Solution: class InputOutString(object): def __init__(self): self.s = "" def getString(self): self.s = input() def printString(self): print(self.s.upper()) str...

Python has several powerful tools for manipulating text strings, including many string methods. To read and parse strings, it’s helpful to know the basics of regular expressions. However, you can often get very far with the third-party parse library as well....
Find a string check this def count_substring(string, sub_string): count =0 for i in range(0,len(string)-len(sub_string)+1): try: if string[i:i+len(sub_string)]==sub_string: count+=1 except IndexError: break return count
prev_item, current_item = string[i-1], string[i] print prev_item, current_item if prev_item == current_item: I am open to any additional comments on more effective approaches for solving a question like this. Solution 1: You can useitertools.groupby(): ...
