Recently obtained some four grade results data, about 500, so the whim can you see whether these results data meet the so-called normal distribution? Do it, so I have this article.The article incidentally introduces some usages of xlrd module and some methods of matplotlib to draw the bar chart and random bar chart of custom data, and provides some related links, which can be used as resources to learn matplotlib and NumPy, and hope to help readers.Se
