Python: Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones of same length

Python Basic - 1: Exercise-142 with Solution

Write a Python program to check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones of the same length in a given string. Return True/False.

Sample Solution:

Python Code:

import re
def test(txt):
    return [len(i) for i in re.findall('0+',txt)]==[len(i) for i in re.findall('1+',txt)]
str1 = "001011"
print("\nOriginal sequence:",str1)
print("Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:")
print(test(str1))
str1 = "01010101"
print("\nOriginal sequence:",str1)
print("Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:")
print(test(str1))
str1 = "00"
print("\nOriginal sequence:",str1)
print("Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:")
print(test(str1))
str1 = "000111000111"
print("\nOriginal sequence:",str1)
print("Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:")
print(test(str1))
str1 = "00011100011"
print("\nOriginal sequence:",str1)
print("Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:")
print(test(str1))
str1 = "0011101"
print("\nOriginal sequence:",str1)
print("Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:")
print(test(str1))

Sample Output:

Original sequence: 001011
Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:
False

Original sequence: 01010101
Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:
True

Original sequence: 00
Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:
False

Original sequence: 000111000111
Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:
True

Original sequence: 00011100011
Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:
False

Original sequence: 0011101
Check if every consecutive sequence of zeroes is followed by a consecutive sequence of ones in the said string:
False
