[FIXED] How do I get a user to enter a binary number and turn it into decimal?

Issue

I am new at python, so I am making a converter from binary to decimal. I want the user to have the opportunity to enter binary and fro my program to output a number in decimal, however everytime I tried to enter it as a binary it came out as the same binary number instead of a decimal. This is the code I have tried:

print ("Please input your number")
n=int(input())
bin_n = bin(n)
print(int(bin_n, 2))

I think maybe its the form thats being input but idk :/

Solution

If the user is entering the number in binary, use the optional base=2 argument when converting the input, not when printing.

n = int(input("Please input your number: "), 2)
print(n)

If the user enters 1001 it will print 9.
