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

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脚本将该文件转换为PSV文件

Answer 1

使用CSV模块通过直接Python脚本从CSV文件到"psv"文件：

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)

使用xlrd包从.xlsx文件到"psv"：

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)])
