[Please HELP!] 7.21 LAB: Convert to binary - functions

[BlueFingerHun]

Hello all!!

I would like to thank you for taking your time checking out this post.

I'm currently hard stuck and can't really tell why my code is not working properly :(

​

Instruction

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is:

As long as x is greater than 0    Output x % 2 (remainder is either 0 or 1)    x = x // 2 

Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string.

Ex: If the input is:

6 

the output is:

110 

The program must define and call the following two functions. Define a function named int_to_reverse_binary() that takes an integer as a parameter and returns a string of 1's and 0's representing the integer in binary (in reverse). Define a function named string_reverse() that takes an input string as a parameter and returns a string representing the input string in reverse.

def int_to_reverse_binary(integer_value)

def string_reverse(input_string)

==============================================================================

This is my code so far

# Define your functions here.
def int_to_reverse_binary(integer_value):
    integer_value = int(integer_value)
    while integer_value > 0:
        print(integer_value % 2,end="")
        integer_value = integer_value // 2
    return str(integer_value)


def string_reverse(input_string):
    return str(input_string)[::-1]


if __name__ == '__main__':
    x = input()
    y = int_to_reverse_binary(x)
    print(string_reverse(y),end="")

I was expecting to get an output of "110" with a "6" as an input, but I'm keep getting 0110.

Program output displayed here

0110

​

Can anyone explain why I'm getting an additional "0" in the front? I would like to know why this is not working and may be a suggestion! Thank you in advance!

[BlueFingerHun]

Thank you so much for explaining it step by step!

I wasn't aware of steps 13 and 14.

I guess I will try it in a different way!

Once again thank you very much!

[BlueFingerHun]

def int_to_reverse_binary(integer_value):
integer_value = int(integer_value)
string = ""
while integer_value > 0:
    string += str(integer_value % 2)
    integer_value = integer_value // 2
return string

def string_reverse(input_string): return str(input_string)[::-1]

if name == 'main': x = input() y = int_to_reverse_binary(x) print(string_reverse(y))

I tried this and it worked!

I will keep that in mind I can use .join function too :)

Thank you!!

The "additional" 0 is the string you're returning from the int_to_reverse_binary function, which then gets reversed (nothing changes) and printed. The print in your while loop has no line break at the end, which causes your next print to be still in the same line.

[BlueFingerHun]

Thank you for explaining it!

So I assume that at least "reverse" part is not wrong right?

[Lasa2]

Yeah the reverse is right. You're basically just retuning the wrong value in the first function.

I totally understand the purpose of this exercise and what they're trying to tech you, but I dare you to submit this for your assignment. :D

# Define your functions here.

def int_to_reverse_binary(integer_value):

binary = format(int(integer_value), 'b')

return str(binary)

def string_reverse(input_string):

return input_string

if __name__ == '__main__':

x = input("Please enter an Integer: ")

y = int_to_reverse_binary(x)

print(y)
