I would normally use My_string = ''.join(My_list)but that doesn't appear to work.... what am I doing wrong? Method #2 : Using map() + split() + list() Since the drawback of above method is that the conversion doesn’t change the datatype of the unit numbers, so if it’s desired to change the data type of number as well, it is suggested to additionally use map() to have list of strings as integers. List comprehension. A new list will be created where you may use the int in each iteration, as shown in the example below. Python Program to Convert Binary Number to Decimal and Vice-Versa A binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols 0 and 1.
