Python对Excel的读写主要有xlrd、xlwt、xlutils、openpyxl、xlsxwriter几种。
1.xlrd主要是用来读取excel文件

import
xlrd
data
=
xlrd.open_workbook(
'abcd.xls'
)
# 打开xls文件
table
=
data.sheets()[
0
]
# 打开第一张表
nrows
=
table.nrows
# 获取表的行数
for
i
in
range
(nrows):
# 循环逐行打印
if
i
=
=
0
:
# 跳过第一行
continue
print
(table.row_values(i)[:
13
])
# 取前十三列

)
sheet.write(
0
,
1
,
'test text'
)
#第0行第一列写入内容
wbk.save(
