如何通过Robot Framework或python脚本将csv（逗号分隔）或xlsx（excel）文件转换为psv（管道分离）文件

Question

我有一个文件，可以是csv文件或xlsx文件，如何通过Robot框架或python脚本将此文件转换为PSV文件

Answer 1

From a CSV file to "psv" file through direct Python scripting using the csv module:

import csv

with open('input.csv', 'rU') as infile, open('output.psv', 'w') as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile, delimiter='|')
    writer.writerows(reader)

From .xlsx file to "psv" using the xlrd package:

import csv
import xlrd

workbook = xlrd.open_workbook('input.xlsx')
sheet = workbook.sheet_by_index(0)        # assume that the data is in the first sheet
with open('output.psv', 'w') as outfile:
    writer = csv.writer(outfile, delimiter='|')
    for i in range(sheet.nrows):
        writer.writerow([cell.value for cell in sheet.row(i)])
