Question

read.txt用逗号这样得到数字。 1,1,1,1 \ n 2,2,2,2 \ n 3,3,3,3

我想通过程序更改每个值，我想更换新的写入值.txt

我在很多方面做过，但我不知道如何找到逗号。

infile = open("read.txt", "r")
outfile = open("write.txt", "w")

total1 =0
count1 =0

line = infile.readline()
while line !="":
    value = float(line)
    total1 = total1 + value
    count1 = count1 + 1
    line = infile.readline()

outfile.write("Column,Sum,Mean,STD,Median,Mode,Min,Max\n")


infile.close()
outfile.close()

首先查看python CSV模块https://docs.python.org/3.6/library/csv.html

但是对于您的原始问题，如果您正在阅读csv文件并希望获得每个＆＃34;值＆＃34;你想要拆分，比如

f = open("someFile.csv")
for line in f:                             # Loop iterates through file by grabbing text seperated by \n
    listOfValuesInLine = line.split(",")   #Returns a list of strings that were sepearted by ","
    print(listOfValuesInLine)              #Prints something like ["value1","value2","value3"] etc
