将TXT转换为CSV python [英] converting TXT to CSV python

问题描述

我有一个txt数据.看起来如下

I have a txt data. it looks as follows

time pos
0.02 1
0.1 2
 ...

，依此类推.因此，每行之间都用空格隔开.我需要将其转换为CSV文件.像

and so on. so the each line is separated with a space. I need to convert it in to a CSV file. like

time,pos
0.02,1
0.1,2
0.15,3

如何使用python做到这一点?这就是我尝试过的

How can I do it with python ? This is what I have tried

time = []
pos = []

def get_data(filename):
    with open(filename, 'r') as csvfile:
        csvFileReader = csv.reader(csvfile)
        next(csvFileReader)
        for row in csvFileReader:
            time.append((row[0].split(' ')[0]))
            pos.append((row[1]))
    return

推荐答案

with open(filename) as infile, open('outfile.csv','w') as outfile: 
    for line in infile: 
        outfile.write(line.replace(' ',','))
