Python: Find the maximum length of a substring of unique character in a given string
Python Itertools: Exercise-24 with Solution
Write a Python program to find the maximum length of a substring in a given string where all the characters of the substring are the same. Use the itertools module to solve the problem.
Sample Solution:
Python Code:
import itertools
def max_sub_string(str1):
return max(len(list(x)) for _, x in itertools.groupby(str1))
str1 = "aaabbccddeeeee"
print("Original string:",str1)
print("Maximum length of a substring with unique characters of the said string:")
print(max_sub_string(str1))
str1 = "c++ exercises"
print("\nOriginal string:",str1)
print("Maximum length of a substring with unique characters of the said string:")
print(max_sub_string(str1))
Sample Output:
Original string: aaabbccddeeeee Maximum length of a substring with unique characters of the said string: 5 Original string: c++ exercises Maximum length of a substring with unique characters of the said string: 2

Inverts a dictionary with non-unique hashable values:
Example:
def tips_collect_dictionary(obj): inv_obj = {} for key, value in obj.items(): inv_obj.setdefault(value, list()).append(key) return inv_obj ages = { "Owen": 25, "Jhon": 25, "Pepe": 15, } print(tips_collect_dictionary(ages))
Output:
{25: ['Owen', 'Jhon'], 15: ['Pepe']}
