python decimal conversion binary

First start the software, because of the mac environment, use Command+N (windows: Ctrl+N) to create a new text-based interactive window, and then Command+S (windows: Ctrl+S) to save the location

Then start editing the code Fn+F5 can start calculation after running

 

is_continue='y'
while is_continue=='Y' or is_continue=='y': 
    def shi(n):
        b = " "
        while n != 0:
            b = str(n % 2)+b
            n //= 2
        return b
    n = int(input("请输入一个十进制数："))
    b = shi(n)
    print("%d的二进制数：%s" % (n, b))
    is_continue=input('\n想再试一次吗？（Y/N）') 

 After Fn+F5 is running, you can start calculating

The above is my sharing of base conversion, I hope you like it.
