In the previous article, we have discussed Python Program to Count Number of Uppercase Letters in a String using Recursion

Given a number, bit position and the task is to get the number after clearing the bit at the given bit position for a given number.

In simple words, it converts all 1’s to 0

let number=7 (111)

Bit position that you want to clear =1

It converts the 1 at index 1 to 0

Number after clearing = 5 (101)

**Bitwise & Operator:**

If both bits are 1, sets each bit to 1.

**Complement operator(~):**

The ones’ complement operator flips the bits of an integer, transforming one into zero and zero into one.

**Examples:**

**Example1:**

**Input:**

Given Number = 60 Bit position(in range 0-31)= 3

**Output:**

The Number after clearing the bit at the given position{ 3 } for a given number{ 60 } = 52

**Example2:**

**Input:**

Given Number = 7 Bit position(in range 0-31)= 1

**Output:**

The Number after clearing the bit at the given position{ 1 } for a given number{ 7 } = 5

## Program to Clear nth Bit of a Number in Python

Below are the ways to get the number after clearing the bit at the given bit position for a given number:

### Method #1: Using **Bitwise **&(and) Operator (Static Input)

**Approach:**

- Give the number as static input and store it in a variable.
- Give the bit position as static input and store it in another variable.
- Apply the left shift operator to 1 and the above-given bit position and store it in another variable.
- Apply the complement operator (which converts 0 to 1 and vice-versa) to the above result and store it in another variable.
- Apply bitwise & operation for the given number and the above result and store it in another variable say rslt_numb.
- Print the number after clearing the bit at the given position for a given number.
- The Exit of the Program.

**Note:** ‘0’ indexing .Give the bit position in range(0-31).

**Below is the implementation:**

# Give the number as static input and store it in a variable. gvn_numb = 60 # Give the bit position as static input and store it in another variable. bitpositin = 3 # Apply the left shift operator to 1 and the above-given bit position and # store it in another variable. numbr_bit = (1 << bitpositin) # Apply the complement operator (which converts 0 to 1 and vice-versa) to the above result # and store it in another variable. complemt = (~numbr_bit) # Apply bitwise & operation for the given number and the above result and store it in # another variable say rslt_numb. rslt_numb = gvn_numb & complemt # Print the number after clearing the bit at the given position for a given number. print("The Number after clearing the bit at the given position{", bitpositin, "} for a given number{", gvn_numb, "} =", rslt_numb)

**Output:**

The Number after clearing the bit at the given position{ 3 } for a given number{ 60 } = 52

### Method #2: Using **Bitwise **&(and) Operator (User Input)

**Approach:**

- Give the number as user input using the int(input()) function and store it in a variable.
- Give the bit position as user input using the int(input()) function and store it in another variable.
- Apply the left shift operator to 1 and the above-given bit position and store it in another variable.
- Apply the complement operator (which converts 0 to 1 and vice-versa) to the above result and store it in another variable.
- Apply bitwise & operation for the given number and the above result and store it in another variable say rslt_numb.
- Print the number after clearing the bit at the given position for a given number.
- The Exit of the Program.

**Below is the implementation:**

# Give the number as user input using the int(input()) function and # store it in a variable. gvn_numb = int(input("Enter some random number = ")) # Give the bit position as user input using the int(input()) function # and store it in another variable. bitpositin = int(input("Enter some random number = ")) # Apply the left shift operator to 1 and the above-given bit position and # store it in another variable. numbr_bit = (1 << bitpositin) # Apply the complement operator (which converts 0 to 1 and vice-versa) to the above result # and store it in another variable. complemt = (~numbr_bit) # Apply bitwise & operation for the given number and the above result and store it in # another variable say rslt_numb. rslt_numb = gvn_numb & complemt # Print the number after clearing the bit at the given position for a given number. print("The Number after clearing the bit at the given position{", bitpositin, "} for a given number{", gvn_numb, "} =", rslt_numb)

**Output:**

Enter some random number = 7 Enter some random number = 1 The Number after clearing the bit at the given position{ 1 } for a given number{ 7 } = 5
