本文实例讲述了Python数据分析之双色球统计单个红和蓝球哪个比例高的方法。分享给大家供大家参考,具体如下:
统计单个红球和蓝球,哪个组合最多,显示前19组数据
#!/usr/bin/python # -*- coding:UTF-8 -*- import pandas as pd import numpy as np import matplotlib.pyplot as plt import operator df = pd.read_table('newdata.txt',header=None,sep=',') tdate = sorted(df.loc[:,0]) # print tdate h1 = df.loc[:,1:7:6].values #取第一列红球和蓝球 # print h1 h2 = df.loc[:,2:7:5].values #取第二列红球和蓝球 h3 = df.loc[:,3:7:4].values h4 = df.loc[:,4:7:3].values h5 = df.loc[:,5:7:2].values h6 = df.loc[:,6:7:1].values # tblue = df.loc[:,7] #将上方切分的所有数据组合到一起 data = np.append(h1, h2, axis = 0) data = np.append(data, h3, axis = 0) data = np.append(data, h4, axis = 0) data = np.append(data, h5, axis = 0) data = np.append(data, h6, axis = 0) # print data data1 = pd.DataFrame(data) # print data1 #写入到一个文件中 data1.to_csv('hldata.csv',index=None,header=None) #读取文件,将组合进行统计并从大到小排序 f = open("hldata.csv") count_dict = {} for line in f.readlines(): line = line.strip() count = count_dict.setdefault(line, 0) count += 1 count_dict[line] = count sorted_count_dict = sorted(count_dict.iteritems(), key=operator.itemgetter(1), reverse=True) # for item in sorted_count_dict: # print "%s,%d" % (item[0], item[1]) # print sorted_count_dict fenzu = pd.DataFrame(sorted_count_dict).set_index([0]) #print fenzu #分别从第一列和第二列取前19个数据放到x y中 x = list(fenzu.index[:19]) y = list(fenzu.values[:19]) print x print y #将x对应数值,不然画图报错 s = pd.Series(range(1,len(x)+1), index=x) #设置画图属性 plt.figure(figsize=(12,6),dpi=80) plt.legend(loc='best') # plt.plot(fenzu,color='red') plt.bar(s,y,alpha=.5, color='r',width=0.8) plt.title('The one red and one blue ball number') plt.xlabel('one red and one blue number') plt.ylabel('times') #可以在图中放置标签字符 # for i in range(0,19): # plt.text(int(i+1.4),25,x[i],color='b',size=10) # plt.text(1.4,20,x[0],color='g',ha='center') #将['1,12', '26,9', '5,13']这样的字符放到图中 plt.xticks(s,x, rotation=10,size=10,ha='left') plt.show()
结果如下:
可以看出红球1和蓝球12出现过的次数最多,其次是红球26和蓝球9
参考:
import matplotlib.pyplot as plt import numpy as np plt.rc('font', family='SimHei', size=13) num = np.array([13325, 9403, 9227, 8651]) ratio = np.array([0.75, 0.76, 0.72, 0.75]) men = num * ratio women = num * (1-ratio) x = ['聊天','支付','团购\n优惠券','在线视频'] width = 0.5 idx = np.arange(len(x)) plt.bar(idx, men, width, color='red', label='男性用户') plt.bar(idx, women, width, bottom=men, color='yellow', label='女性用户') plt.xlabel('应用类别') plt.ylabel('男女分布') plt.xticks(idx+width/2, x, rotation=40) plt.legend()
希望本文所述对大家Python程序设计有所帮助。
