Python读取Excel

1、python先安装xlrd模块，打开命令行，输入pip install xlrd

2、python读取excel文件的步骤：1. 打开excel工作簿workbook，2. 定位到工作表sheet，3. 定位行和列，读取数据；

3、读取excel示例代码如下：

-- coding: utf-8 --

import xlrd
def read_excel():
# 打开文件
workbook = xlrd.open_workbook(r'D:\Program Files\JetBrains\PyCharm Community Edition 2020.3.3\jbr\bin\D\pythonProject\com\mysql\001test.xls')
# 获取所有sheet
print(workbook.sheet_names()) # [u'sheet1', u'sheet2']
#获取sheet2
sheet2_name= workbook.sheet_names()[0]
print (sheet2_name)
# 根据sheet索引或者名称获取sheet内容
sheet2 = workbook.sheet_by_name(sheet2_name)
# sheet的名称，行数，列数
print (sheet2.name,sheet2.nrows,sheet2.ncols)
rows = sheet2.row_values(0) # 获取第1行内容
cols = sheet2.col_values(0) # 获取第1列内容
print (rows)
print (cols)
#获取单元格内容的三种方法
print (sheet2.cell(0,0).value)
print (sheet2.cell_value(0,1))
print (sheet2.row(2)[0].value)
# 获取单元格内容的数据类型
print (sheet2.cell(0,0).ctype)
if name == 'main':
read_excel()

附 获取pcharm文件路径：
1、选中项目中要读取的excel文件，右键copy path,

2、再选absulute path

3、复制到路径贴到如下代码块中
workbook = xlrd.open_workbook(r'D:\Program Files\JetBrains\PyCharm Community Edition 2020.3.3\jbr\bin\D\pythonProject\com\mysql\001test.xls')
