我正在尝试运行此程序

import matplotlib.pyplot as plt
import numpy

plt.plot([1, 2, 3],[5, 7, 4])
plt.show()

我收到一条错误消息:ImportError:没有名为pyplot的模块

我已经在Windows 8 64位上安装了matplotlib,使用来自bash的pip命令安装了Python 2.7,我也更新了它,结果收到了这条消息:

Aneta@AKZ-5K-Computer:~$ C:/Python27/Scripts/pip install --upgrade matplotlib

当我尝试安装pyplot时,我得到了这个按摩:

Aneta@AKZ-5K-Computer:~$ C:/Python27/Scripts/pip install pyplot
Collecting pyplot

我有这个简单的小程序,它不起作用.我希望程序不断询问用户我的名字,直到他们猜到.

第一次尝试后,程序将抛出错误消息.我无法解决问题所在.

name = "not_aneta"

while name != "aneta":
    name = input("What is my name? ")

if name == "aneta":
    print "You guessed my name!"

当我运行它时,我收到一条错误消息:

Traceback (most recent call last):
  File "C:\Users\Aneta\Desktop\guess_my_name.py", line 4, in <module>
    name = input("What is my name? ")
  File "<string>", line 1, in <module>
NameError: name 'aneta' is not defined
