After writing the above code (python square a number), Ones you will print ” number(4) “ then the output will appear as a “ 16 ”. Here, def is used to define a function and “x” is the number which will multiply. You can refer to the below screenshot for python square a number. Python square a numberWe can also square a number by using exponent operator ” ** “ and it will multiply the number in easy way. Example:
After writing the above code (python square a number), Ones you will print ” a “ then the output will appear as a “ 25 ”. You can refer to the below screenshot for python square a number How to square a number in PythonPython square a number listTo square a number list in python, it will square each number in the list and it will multiply each number by itself. Example:
After writing the above code (python square a number list), Ones you will print ” v**2 “ then the output will appear as a “ 1 9 25 49 ”. Here, the list will iterate and it will be multiplied by 2. You can refer to the below screenshot for python square a number list. Python square a number listWe can also square a number list by using list comprehension to square each number in the list. Example:
After writing the above code (python square a number list), Ones you will print ” value “ then the output will appear as a “ [1 9 25 49] ”. Here, the list number will be multiplied by 2. You can refer to the below screenshot for python square a number list. How to Python square a number listPython square root of a numberIn python, we can calculate the square root of a number in python, by using the exponent operators. Example:
After writing the above code (python square root of a number), Ones you will print “( number, number_square)” then the output will appear as a “ Square root of 9.000 is 3.000 ”. Here, we store the number and the exponent operator will find the square root. You can refer to the below screenshot for the python square root of a number. Python square root of a numberPython square number checkIn Python, to check whether the number is a perfect square or not, use the power operator ” ** “ with exponent as 0.5 and also modulus operator “ % “ to get the remainder. It will check and return the output as true or false respectively. Example:
After writing the above code (python square number check), Ones you will print ” result “ then the output will appear as a “ True ”. Here, 9 is the perfect square and the remainder is 0 because it is the whole number. You can refer to the below screenshot for the python square number check. Python square number checkWe will also see when the number is not a perfect square and the remainder is not equal to 0. Then it will give false as an output. Example:
Here, 8 is not the perfect square and the remainder is not equal to 0. So, the output is ” False ” as it is not the perfect square. You can refer to the below screenshot for the python square number check. Python square number while loopIn python, while loop repeats the sequence many times until the condition gets false. Here, the square of a number using while loop works till the condition gets false and it will return the output as a square of the number. Example:
After writing the above code (python square number while loop), Ones you will print ” (number1 ** 2)” then the output will appear as a “ 1 4 9 16 ” which is square of the number. Here, the variable number1 inside the loop iterates from 1 to 4. You can refer to the below screenshot for python square number while loop. Python square number while loopSquare root function in pythonPython math module contains many useful functions and it also includes python square root function sqrt() for calculating the square root. Firstly, we need to import math module.
After writing the above code (square root function in python), Ones you will print ” a ” then the output will appear as an “ 8.0”. Here, we will use math.sqrt() for calculating the square roots and it will return floating-point numbers as output. Square root function in pythonPython square roots with list comprehensionTo get the square roots from a list we will use list comprehension. We will first import the math module in which the math.sqrt() function available. Then we make the list with random numbers and the loop is used to iterate through all the elements in the list.
After writing the above code (python square roots with list comprehension), Ones you will print “sqr_root” then the output will appear as an “[6.0, 7.0, 6.48074069840786, 5.0, 9.0]”. Here, we will use math.sqrt(num) for calculating the square roots of the list and the sqr_root list has the square root for each number in the original value list. How to do exponents in pythonThe double asterisk ” ** “ operator is used to calculate the exponential value. The number to be multiplied by itself is called the base and the number of times it is to be multiplied is the exponent. Example:
After writing the above code (how to do exponents in python), Once you will print ” base ** exponent “ then the output will appear as a “ 9 ”. Here, the base is 3 and the exponent is 2 and it will return the corresponding value. You can refer to the below screenshot on how to do exponents in python.
