‘‘‘=================xlrd负责读取excel，功能上只能读===============================================
‘‘‘

myfile = xlrd.open_workbook(r‘D:\python_test\cc.xlsx‘)#打开excel
sheets = myfile.sheet_names()#读取sheet名
print(sheets)



‘‘‘注意，参数首位为0
‘‘‘
first_table = myfile.sheet_by_index(0)#打开第0个sheet
print(first_table.name)#返回sheet名
print(first_table.nrows)#返回sheet行数
print(first_table.ncols)#返回sheet列数

#返回第一行
first_row = first_table.row_values(0)
print(first_row)

#返回第一列
first_col = first_table.col_values(0)
print(first_col)

#返回指定单元格，第10行，第1列
target = first_table.cell(10,1).value
print(target)
