[英]converting TXT to CSV python
我有一个txt数据。 它看起来如下
time pos
0.02 1
0.1 2
...
等等。 因此每行之间用空格隔开。 我需要将其转换为CSV文件。 喜欢
time,pos
0.02,1
0.1,2
0.15,3
我该如何使用python呢? 这就是我尝试过的
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
with open(filename) as infile, open('outfile.csv','w') as outfile:
for line in infile:
outfile.write(line.replace(' ',','))
从这里 :
import csv
with open(filename, newline='') as f:
reader = csv.reader(f, delimiter=' ')
for row in reader:
print(row)
对于写入,只需使用默认选项,它将使用逗号作为分隔符保存文件。
尝试:
import pandas as pd
with open(filename, 'r') as fo:
data = fo.readlines()
for d in range(len(data)):
if d==0:
column_headings = data[d].split()
data_to_insert = data[d].split()
pd.DataFrame(data_to_insert).to_excel('csv_file.csv', header=False, index=False, columns = column_headings))
您可以使用此:
import csv
time = []
pos = []
def get_data(filename):
with open(filename, 'r') as csvfile:
csvfile1 = csv.reader(csvfile, delimiter=' ')
with open(filename.replace('.txt','.csv'), 'w') as csvfile:
writer = csv.writer(csvfile, delimiter=',')
for row in csvfile1:
writer.writerow(row)
