How does python e represent

Python e representation method: use the [exp()] method, the code is [import math;math.exp(x);], [exp()] cannot be accessed directly, and the math module needs to be imported. , calling this method through a static object.

The operating environment of this tutorial: Windows 7 system, python version 3.9, DELL G3 computer.

Python e representation method:

exp() method returns the exponent of x, ex.

Syntax

import math
math.exp( x )

Note: exp() cannot be accessed directly Yes, you need to import the math module and call this method through a static object.

Parameters

x -- Numeric expression.

Return value

Returns the exponent of x, ex.

Example

The following shows an example of using the exp() method:

#!/usr/bin/python
import math   # 导入 math 模块
print "math.exp(-45.17) : ", math.exp(-45.17)
print "math.exp(100.12) : ", math.exp(100.12)
print "math.exp(100.72) : ", math.exp(100.72)
print "math.exp(119L) : ", math.exp(119L)
print "math.exp(math.pi) : ", math.exp(math.pi)

The output result after running the above example is:

math.exp(-45.17) :  2.41500621326e-20
math.exp(100.12) :  3.03084361407e+43
math.exp(100.72) :  5.52255713025e+43
math.exp(119L) :  4.7978133273e+51
math.exp(math.pi) :  23.1406926328
