How to write square root in Python?Python has a predefined sqrt() function that returns the square root of a number. It defines the square root of a value that multiplies itself to give a number. The sqrt() function is not used directly to find the square root of a given number, so we need to use a math module to call the sqrt() function in Python. For example, the square root of 144 is 12. ![]() Using math.sqrt() methodThe sqrt() function is an inbuilt function that returns the square root of any number. Following are the steps to find the square root of a number.
Let's create a Python program to find the square root of a number. SqrRoot.py Output: ![]() Let's create a python program that finds the square root of a decimal numbers. SqrRoot.py Output: ![]() In the following program, we have read a number form the user and find the square root. SqRoot_Usr.py Output: ![]() Using math.pow() functionThe pow() is an inbuilt function that is used in Python to return the power of a number. It has two parameters. The first parameter defines the number and second parameter defines the power raise to that number. Pow_Sqrt.py Output: ![]() Using ** OperatorWe can also use the exponent operator to find the square root of the number. The operator can be applied between two operands. For example, x**y. It means that left operand raised to the power of right. Following are the steps to find the square root of a number. Step 1. Define a function and pass the value as an argument. Step 2. If the defined number is less than 0 or negative, it returns nothing. Step 3. Use the exponential ** sign to find the power of a number. Step 4. Take the numeric value from the user. Step 5. Call the function and store its output to a variable. Step 6. Display the Square Root of a number in Python. Step 7. Exit from the program. Let's implement the above steps in a Python program and calculate the square root of a number. SqrtFun.py Output: ![]() As we can see in the above example, first we take an input (number) from the user and then use the exponent ** operator to find out the power of a number. Where 0.5 is equal to √ (root symbol) to raise the power of a given number. Let's create a Python program that finds the square root of between the specified range. In the following program, we have found the square root of all the number between 0 to 50. Sqrloop.py Output: ![]()
