Numpy provides a wide range of mathematical functions that can be performed on arrays. Let's explore three different types of math functions in NumPy: Trigonometric Functions Arithmetic Functions Rounding Functions 1. Trigonometric Functions NumPy provid
函数Functions Python函数使用def来定义函数: def sign(x): if x > 0: return 'positive' elif x < 0: return 'negative' else: return 'zero' for x in [-1, 0, 1]: print sign(x) # Prints "negative", "zero", "positive" 我们常常使用可选参数来定义函数: def hello(name, loud=False)...
