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 same. Use 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

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
