python读取excel中单元格的内容返回的有5种类型，即上面例子中的ctype:

ctype： 

0   empty

1   string

2   number

3   date

4   boolean

5   Error

1 # coding=utf-8
2 import xlrd

5 reload(sys)
6 sys.setdefaultencoding('utf-8')
7 import traceback
8 from datetime import datetime

12 class excelHandle:
13     def decode(self, filename, sheetname):
14         try:
15             filename = filename.decode('utf-8')
16             sheetname = sheetname.decode('utf-8')
17         except Exception:

27         all_content = []
28         for i in range(rows):

33                 if ctype == 2 and cell % 1 == 0:  # 如果是整形
34                     cell = int(cell)

40                     cell = True if cell == 1 else False
41                 row_content.append(cell)

49     filename = r'G:\test\ctype.xls'

51     eh.read_excel(filename, sheetname)

(2) 稍微修改了一下，读取excel所有sheets的内容。

# coding=utf-8

# reload(sys)
# sys.setdefaultencoding('utf-8')

#     except Exception:
#         print
#         traceback.print_exc()
#     return filename, sheetname

def read_excel(self, filename):
# filename, sheetname = self.decode(filename, sheetname)
rbook = xlrd.open_workbook(filename)
sheets = rbook.sheet_names()  # 获取所有sheet名
allSheetsContent=[]
for sh in sheets:
sheet = rbook.sheet_by_name(sh)
rows = sheet.nrows
cols = sheet.ncols
sheetContent = []
for i in range(1,rows):
rowContent = []
for j in range(cols):
ctype = sheet.cell(i, j).ctype  # 表格的数据类型

cell = int(cell)
elif ctype == 3:

date = datetime(*xldate_as_tuple(cell, 0))
cell = date.strftime('%Y/%d/%m %H:%M:%S')
elif ctype == 4:
cell = True if cell == 1 else False
rowContent.append(cell)
allSheetsContent.append(rowContent)
# sheetContent.append(rowContent)

return allSheetsContent
