Given a number, and we have to calculate its square in Python.

给定一个数字，我们必须在Python中计算其平方。

Example:

例：

Input: Enter an integer numbers: 8 Output: Square of 8 is 64

Calculating square is a basic operation in mathematics; here we are calculating the square of a given number by using 3 methods.

计算平方是数学中的基本运算。在这里，我们使用3种方法计算给定数字的平方。

By multiplying numbers two times: (number*number)

将数字乘以两倍：( 数字*数字)

By using Exponent Operator (**): (number**2)

通过使用指数运算符( ** )：( 数字** 2)

By using math.pow() method: (math.pow(number,2)

通过使用math.pow()方法： (math.pow(number，2)

1)将数字相乘两次：(数字*数字) (1) By multiplying numbers two times: (number*number))

To find the square of a number - simple multiple the number two times.

要查找数字的平方-将数字简单乘以两次。

Program:

程序：

# Python program to calculate square of a number # Method 1 (using number*number) # input a number number = int (raw_input ("Enter an integer number: ")) # calculate square square = number*number # print print "Square of {0} is {1} ".format (number, square)

Output

输出量

Enter an integer number: 8 Square of 8 is 64 2)通过使用指数运算符(**)：(数字** 2) (2) By using Exponent Operator (**): (number**2))

The another way is to find the square of a given number is to use Exponent Operator (**), it returns the exponential power. This operator is represented by **

另一种查找给定数字平方的方法是使用指数运算符 ( ** )，它返回指数幂。该运算符由**表示

Example: Statement m**n will be calculated as "m to the power of n".

示例：语句m ** n将计算为
