# Python Program to Convert Binary to Hexadecimal

In this article, we've created some programs in Python, to convert any binary number entered by user to its equivalent hexadecimal value. Here are the list of programs:

- Binary to Hexadecimal with User-defined Code
- Binary to Hexadecimal using
**int()**and**hex()**Methods

**Note - **Before creating these programs, if you're not aware about some steps used for the conversion, refer to
Binary to Hexadecimal Conversion Steps and Formula to get every required things.

## Binary to Hexadecimal with User-defined Code

To convert binary to hexadecimal number in Python, you have to ask from user to enter a number in binary number system to convert that number into hexadecimal number system as shown in the program given here.

The question is, **write a Python program to convert binary to hexadecimal using while loop**. Here is its answer:

print("Enter the Binary Number: ") bnum = int(input()) hex = 0 mul = 1 chk = 1 i = 0 hnum = [] while bnum!=0: rem = bnum%10 hex = hex + (rem*mul) if chk%4==0: if hex<10: hex = hex+48 val = chr(hex) hnum.insert(i, val) else: hex = hex+55 val = chr(hex) hnum.insert(i, val) mul = 1 hex = 0 chk = 1 i = i+1 else: mul = mul*2 chk = chk+1 bnum = int(bnum/10) if chk!=1: hex = hex+48 val = chr(hex) hnum.insert(i, val) if chk==1: i = i-1 print("\nEquivalent Hexadecimal Value = ", end="") while i>=0: print(end=hnum[i]) i = i-1 print()

Here is the initial output produced by this Python program:

Now supply the input say **111011** and press `ENTER`

key to convert it into its equivalent
hexadecimal value and print the hexadecimal value on output as shown in the snapshot given below:

**Note - **The **chr()** method is used to returns equivalent character to the Unicode specified as its argument.

The **insert()** method is used to insert an element to the list. Therefore the following statement:

`hnum.insert(i, val)`

can be treated as:

hnum[i] = val

That is, the value of **val** variable gets initialized to **i ^{th}** index of

**hnum**list.

The dry run of above program, with user input **111011** goes like:

- Initial values,
**bnum=111011**(entered by user),**hex=0**,**mul=1**,**chk=1**,**i=0** - The condition (of
*while loop*)**bnum!=0**or**111011!=0**evaluates to be true, therefore program flow goes inside the loop - Inside the loop, the first statement, that is:

`rem = bnum%10`

gets executed - Therefore
**bnum%10**or**111011%10**or**1**gets initialized to**rem** **hex + (rem*mul)**or**0 + (1*1)**or**1**gets initialized to**hex**- The condition (of
**if**)**chk%4==0**or**1%4==0**evaluates to be false, therefore program flow does not goes inside this**if**'s block, rather it goes to its**else**'s part - And
**mul*2**or**1*2**or**2**gets initialized to**mul**. So**mul=2** **chk+1**or**1+1**or**2**gets initialized to**chk**. So**chk=2**- And finally,
**int(bnum/10)**or**int(111011/10)**or**11101**gets initialized to**bnum** - The condition (of
*while loop*)**bnum!=0**again gets evaluated with new value of**bnum**. That is,**bnum!=0**or**11101!=0**evaluates to be true again, therefore program flow goes inside the loop again. This process continues, until the condition evaluates to be false - In this way, the binary number entered by user gets converted into its equivalent hexadecimal value

The condition:

`if chk%4==0:`

is applied to check four-four pair of binary digits to convert into its equivalent hexadecimal digit.

And the condition:

`if hex<10:`

is applied to check whether the equivalent hexadecimal digit is less than 10 or not. That is, if it is 10, 11, 12, ..., 15. Then we've to store A, B, C, ..., F in place of these.

For example, if hex digit is **12**, then the condition **hex<10** evaluates to be false, therefore its
**else**'s counterpart gets executed. And in place of **12** we've to store **C**. Therefore **C** gets
stored through following block of code:

hex = hex+55 val = chr(hex) hnum.insert(i, val)

Since **hex=12**, therefore **hex+55** or **12+55** or **67** gets initialized to **hex**. And
**chr(hex)** returns the corresponding character equals to the Unicode specified as its argument, that is the
value of **hex**, **67**. Since 67 is the ASCII value of **C**. Therefore **val = C**. And the value of
**val** gets initialized to **i ^{th}** index of

**hnum**.

#### Modified Version of Previous Program

This program is the modified version of previous one. The **end=** is used to skip printing of an automatic newline using **print()**.

print("Enter the Binary Number: ", end="") bnum = int(input()) hex = 0 mul = 1 chk = 1 i = 0 hnum = [] while bnum!=0: rem = bnum%10 hex = hex + (rem*mul) if chk%4==0: if hex<10: hnum.insert(i, chr(hex+48)) else: hnum.insert(i, chr(hex+55)) mul = 1 hex = 0 chk = 1 i = i+1 else: mul = mul*2 chk = chk+1 bnum = int(bnum/10) if chk!=1: hnum.insert(i, chr(hex+48)) if chk==1: i = i-1 print("\nEquivalent Hexadecimal Value = ", end="") while i>=0: print(end=hnum[i]) i = i-1 print()

Here is its sample run with user input, **1101110**:

## Binary to Hexadecimal using int() and hex()

This program uses **int()** and **hex()** methods to do the job of converting binary to hexadecimal.

print("Enter the Binary Number: ", end="") bnum = input() b = int(bnum, 2) hdnum = hex(b) print("\nEquivalent Hexadecimal Value = ", hdnum)

Here is its sample run with user input **111101** as binary number:

While receiving the input, we've not specified the type, therefore the entered value by user gets treated as a
string type value. And using **int()** method with 2 as its second argument, converted the given value into
an integer type value of base 2, that is binary number.

And using **hex()** method, the binary number gets converted into its equivalent hexadecimal value.

#### Modified Version of Previous Program

This program uses **hdnum[2:]** to print element(s) starting from second index. That is, the first
two characters gets skipped after applying **[2:]**. And **upper()** is used to capitalize the lowercase character.

print("Enter the Binary Number: ", end="") bnum = input() b = int(bnum, 2) hdnum = hex(b) print("\nEquivalent Hexadecimal Value = ", hdnum[2:].upper())

Here is its sample run with user input, **11100111**:
