calculate binary number from input in python

To calculate the binary representation of an input number in Python, you can use the bin() function. The bin() function takes an integer as input and returns its binary representation as a string.

Here's an example code snippet:

main.py
dec_num = int(input("Enter an integer: "))   # take input from user
bin_num = bin(dec_num)                       # convert decimal to binary
print(f"The binary representation of {dec_num} is {bin_num}.")   # print binary representation

In this code, we first take an integer input from the user using the input() function. We then convert the input number to binary using the bin() function and store the result in the variable bin_num. Finally, we print the binary representation using a formatted string.

For instance, if the user enters 5 as input, the output will be:

main.py
Enter an integer: 5
The binary representation of 5 is 0b101.
