How to count the two-color ball high-frequency data by Python
This article mainly introduces "Python how to count high frequency data of two-color ball". In daily operation, I believe many people have doubts about Python how to count high frequency data of two-color ball. Xiaobian consulted all kinds of materials and sorted out simple and easy operation methods. I hope to help you answer the doubts of "Python how to count high frequency data of two-color ball"! Next, please follow the small series to learn together!
Step1: Basic data preparation (obtained by crawler), the following is all the data from the first issue of 03 years to today, up to now a total of 2549 issues, balls.txt file content is as follows:
Step2: Analyze the data characteristics and data processing method selection, directly on the code as follows:
#import Counterfrom collections import Counter
def readfile(): red_lists=[] blue_lists=[] #Open file and get file handle with open("./ balls.txt", "r",encoding='utf-8') as fp: #Start reading files and return a list list1=fp.readlines() #traverse the entire file content for i in range(len(list1)): #Replace\n characters with spaces list2=str(list1[i]).replace("\n","").split(" ") for j in range(len(list2)): if j==6: #Blue ball put in blue_lists list blue_lists.append(list2[j]) else: #Red ball put in red_lists list red_lists.append(list2[j]) #Counter can quickly and easily do some statistical operations on some objects, here is the number of times the data in the list appears statistics, return a tuple red_count=Counter(red_lists) blue_count=Counter(blue_lists) #most_common can be used to count and sort the most common elements in a list or string, and return a list k = red_count.most_common(len(red_count)) #Output the six red balls with the highest frequency print("the red ball:",k[:6]) l = blue_count.most_common(len(blue_count)) #Output the six most frequent blue balls print("the blue ball:",l[:6]) if __name__=="__main__": readfile()
Step3: The results are as follows:
Step4: Perform Result Verification:
At this point, the study of "Python how to count high frequency data of two-color ball" is over, hoping to solve everyone's doubts. Theory and practice can better match to help you learn, go and try it!
