In NumPy, in addition to basic arithmetic operations, multi-dimensional arrays also have some very useful functions built-in, which can speed up our scientific calculations. Simple function Let's take a look at the more common arithmetic functions. Before using, we first construct an array: arr...
But often we don’t need the full matplotlib library in our programs,and this is where Pyplot comes in handy. 但是我们的程序中通常不需要完整的matplotlib库,这就是Pyplot的用武之地。 Pyplot is a collection of functions that make matplotlib work like Matlab,which you may be familiar with. ...
The float printing routines use an accurate but much more computationally demanding algorithm to compute the number of digits after the decimal point. Alternatively,Python’s builtinroundfunction uses a more accurate but slower algorithm for 64-bit floating point values: 代码语言:javascript 代码运行次...
