Question

please answer in python

print Cannot divide anything but numbers. else - print n. 5. (+15) Write a function bin2dec( ) that takes a string representation of any length binary number and returns the decimal equivalent without using any type_conversions. Remember that the binary representation of a number has a power of 2 in each position, starting with 2° in the right most position and increasing by 1 as it moves left (e.g. 242'2') 6 >>> binadec('110') 2721862.1 >>> bin2ded('11111111) 9127.24 -. +?° >>> bin2dec('1') 255 def bin 2 dec (sh) = 4 go Character ech Chracter through the strong -10 n=Str.count(17 fostet w ves= a + t24. retun ves.

Answer 1

import math
def bin2dec(binStr):
count=len(binStr);
decimalVal=0;
for i in range(0,count):
decimalVal=decimalVal+(int(binStr[count-i-1])*math.pow(2,i));
return decimalVal;
  
  
def main():
print(bin2dec('110'));
print(bin2dec('11111111'));
print(bin2dec('1'));
if __name__=="__main__":
main();

1 import math 2- def bin2dec(binStr): count=len(binStr); decimalval=0; for i in range(0,count): decimalval=decimalval+(int(binStr[count-i-1]) math. pow(2,1)); return decimalval; 10 def main(): print(bin2dec('110')); print(bin2dec('11111111')); print(bin2dec('1')); 14- if _name__=="_main__": main();

Expected output:

16.0 255.0 1.0
