Python: Find maximum length of consecutive 0’s in a given binary string

Python String: Exercise-64 with Solution

Write a Python program to find maximum length of consecutive 0’s in a given binary string.

Sample Solution:-

Python Code:

def max_consecutive_0(input_str): 
     return  max(map(len,input_str.split('1')))
str1 = '111000010000110'
print("Original string:" + str1)
print("Maximum length of consecutive 0’s:")
print(max_consecutive_0(str1))
str1 = '111000111'
print("Original string:" + str1)
print("Maximum length of consecutive 0’s:")
print(max_consecutive_0(str1))

Sample Output:

Original string:111000010000110
Maximum length of consecutive 0’s:
4
Original string:111000111
Maximum length of consecutive 0’s:
3

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")
