Python has a built-in module that you can use for mathematical tasks. Themathmodule has a set of methods and constants. Math Methods MethodDescription math.acos()Returns the arc cosine of a number math.acosh()Returns the inverse hyperbolic cosine of a number ...
MathModule ||--o{ Function : has 在这幅图中,MathModule表示数学模块,包含不同的函数和常量,而Function则描述了我们定义的函数的结构。 4. 结论 今天,我们学习了如何在Python中导入math模块,并定义一个使用该模块功能的简单函数。通过几个清晰的步骤和代码示例,相信您现在已经掌握了这些基本概念。 在今后的编程...
在下面的示例中,我们将使用math模块中的两个函数:求平方根的函数sqrt和计算正弦值的函数sin。 importmath# 计算平方根num=16square_root=math.sqrt(num)print(f"The square root of{num}is{square_root}")# 计算正弦值angle=math.pi/2sin_value=math.sin(angle)print(f"The sine value of{angle}is{sin_...
Python的math模块是Python标准库中提供数学函数和常数的模块。它包含了一系列常用的数学函数,以及一些常用的数学常数。math模块是Python中进行数学计算的重要工具。 math模块的主...
The Python math module provides a function, exp(), that lets you calculate the natural exponent of a number. You can find the value as follows: Python >>> math.exp(21) 1318815734.4832146 >>> math.exp(-1.2) 0.30119421191220214 The input number can be positive or negative, and the funct...
When you have imported themathmodule, you can start using methods and constants of the module. Themath.sqrt()method for example, returns the square root of a number: Example importmath x = math.sqrt(64) print(x) Try it Yourself » ...
python import math as m # 使用别名访问math模块中的函数 print(m.sqrt(16)) # 输出: 4.0 # 或者为特定函数指定别名 from math import sqrt as square_root print(square_root(16)) # 输出: 4.0 在这个例子中,我们为math模块指定了别名m,并为sqrt函数指定了别名square_root。
