pyplotis a sub-module of matplotlibwhich doesn't get imported with a simple import matplotlib.
pyplot是一个子模块，matplotlib它不会通过简单的import matplotlib.
>>> import matplotlib
>>> print matplotlib.pyplot
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
>>> import matplotlib.pyplot
>>>
It seems customary to do: import matplotlib.pyplot as pltat which time you can use the various functions and classes it contains:
似乎习惯这样做： import matplotlib.pyplot as plt此时您可以使用它包含的各种函数和类：
p = plt.plot(...)

Did you import it? Importing matplotlibis not enough.
你导入了吗？进口matplotlib还不够。
>>> import matplotlib
>>> matplotlib.pyplot
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
but
但
>>> import matplotlib.pyplot
>>> matplotlib.pyplot
works.
作品。
pyplot is a submodule of matplotlib and not immediately imported when you import matplotlib.
pyplot 是 matplotlib 的子模块，在导入 matplotlib 时不会立即导入。
The most common form of importing pyplot is
导入 pyplot 的最常见形式是
import matplotlib.pyplot as plt
Thus, your statements won't be too long, e.g.
因此，您的陈述不会太长，例如
plt.plot([1,2,3,4,5])
instead of
代替
matplotlib.pyplot.plot([1,2,3,4,5])
And: pyplotis not a function, it's a module! So don't call it, use the functions defined insidethis module instead. See my example above
并且：pyplot不是一个函数，它是一个模块！所以，不要把它，使用定义的函数里面这个模块来代替。看我上面的例子
