python如何八进制转十进制,如何使用Python将八进制转换为十进制

I have this little homework assignment and I needed to convert decimal to octal and then octal to decimal. I did the first part and can not figure out the second to save my life. The first part went like this:

decimal = int(input("Enter a decimal integer greater than 0: "))

print("Quotient Remainder Octal")

bstring = " "

while decimal > 0:

remainder = decimal % 8

decimal = decimal // 8

bstring = str(remainder) + bstring

print ("%5d%8d%12s" % (decimal, remainder, bstring))

print("The octal representation is", bstring)

I read how to convert it here: Octal to Decimal but have no clue how to turn it into code. Any help is appreciated. Thank you.

From decimal to octal:

oct(42) # '052'

Octal to decimal

int('052', 8) # 42

If you want to return octal as a string then you might want to wrap it in str.
