Python – Convert Binary tuple to Integer
Given Binary Tuple representing binary representation of number, convert to integer.
Input : test_tup = (1, 1, 0)
Output : 6
Explanation : 4 + 2 = 6.Input : test_tup = (1, 1, 1)
Output : 7
Explanation : 4 + 2 + 1 = 7.
Method #1 : Using join() + list comprehension + int()
In this, we concatenate the binary tuples in string format using join() and str(), then convert to integer by mentioning base as 2.
Python3
# Python3 code to demonstrate working of # Convert Binary tuple to Integer# Using join() + list comprehension + int() # initializing tupletest_tup = (1, 1, 0, 1, 0, 0, 1) # printing original tupleprint("The original tuple is : " + str(test_tup)) # using int() with base to get actual numberres = int("".join(str(ele) for ele in test_tup), 2) # printing result print("Decimal number is : " + str(res)) |
The original tuple is : (1, 1, 0, 1, 0, 0, 1) Decimal number is : 105
Method #2 : Using bit shift and | operator
In this we perform left bit shift and use or operator to get binary addition and hence compute the result.

The original tuple is : (1, 1, 0, 1, 0, 0, 1) Decimal number is : 105
