所以我试图从文件中读取一个列表，然后将其绘制成图形。
这是我的代码
with open('the list') as f:
listoflang = [tuple(map( str ,i.split())) for i in f]
print listoflang
import numpy as np
import matplotlib.pyplot as plt
top= listoflang
labels, ys = zip(*top)
xs = np.arange(len(labels))
width = 1
fig = plt.figure()
ax = fig.gca()
ax.bar(xs, ys, width, align='center')
ax.set_xticks(xs)
ax.set_xticklabels(labels)
ax.set_yticks(ys)
plt.savefig('graph.png')
listoflang看起来像这样
[（＆＃39; mysql＆＃39;，2），（＆＃39; unix＆＃39;，2），（＆＃39; linux＆＃39;，1），（＆＃39; perl＆＃ 39;，2），（＆＃39; php＆＃39;，4），（＆＃39; java＆＃39;，25），（＆＃39; javascript（初学者）＆＃39;，1），（ ＆＃39; ruby＆＃39;，2），（＆＃39; html＆＃39;，9），（＆＃39; android＆＃39;，1），（＆＃39; css＆＃39;，4） ，（＆＃39; shell＆＃39;，1），（＆＃39; c / c ++＆＃39;，1），（＆＃39; python＆＃39;，29），（＆＃39; javascript＆＃39;，3），（＆＃39; c＃（初学者）＆＃39;，1），（＆＃39; jsp＆＃39;，1），（＆＃39; sql＆＃39;，2） ，（＆＃39; html＆amp; css＆＃39;，1），（＆＃39; c＆＃39;，37），（＆＃39; python（basics＆＃39;，1），（＆＃39; c ++＆＃39;，25），（＆＃39; cpp＆＃39;，5）]
但这会归还

我可能做错了什么？ 在此先感谢!!
答案 0 :(得分：-1)
我在Python 3.5.2和numpy 1.12.1上使用numpy数组和掩码的构造有类似的问题。
构造错误显示的位置：
ret[ix,(mask==zeroes)] = 0
其中mask具有与ret的第一维互补的尺寸，而mask和0是具有相同尺寸的二进制数组（仅零和一些）。
警告过滤器配置为生成错误时
with warnings.catch_warnings():
warnings.simplefilter("error") # "ignore" if not solved quickly
ret [ix，（mask == zeroes）] = 0
当警告过滤器配置为生成错误时，我会更频繁地使用 问题。当过滤器设置为＆＃34;警告＆＃34;时，错误消息也会改变。
with warnings.catch_warnings():
warnings.simplefilter("error") # "ignore" if not solved quickly
ret[ix,(mask==zeroes)] = 0
我不确定正确的解决方法是什么。
