The abs() function in Python is a built-in function that returns the absolute value of a number. In other words, it returns the positive magnitude of a given numeric value, regardless of its sign. For example: abs(5) returns 5 because the absolute value of 5 is 5. abs(-7) returns...

1.变量可以指向函数 以Python内置的abs()函数为例,调用函数: >>> abs(-19) # 函数调用 19 1. 2. 如果只写abs呢 >>> abs # 函数本身 <built-in function abs> 1. 2. 结果表明,abs是一个内置的函数,abs(-19)是函数调用,而abs是函数本身。 获取函数返回结果,可以把结果赋值给一个变量 >>> x=abs...
