python操作Excel表格_python sheet

一、python操作Excel表格

读取一个Excel的基本流程
1. 双击打开一个Excel文件
2. 选择sheet
3. 对sheet里面的东西进行操作

在python中我们使用第三方模块 openpyxl模块操作Excel

ps:这个模块不是python自带的 是第三方模块需要我们下载的
进入终端输入: pip install openpyxl
如果想要下载快点:百度搜索 python第三方源

from openpyxl import load_workbook

# 1. 打开Excel文件 
workbook = load_workbook("p1.xlsx")
# 2. 选择sheet
# 2.1 获取所有sheet
# print(workbook.sheetnames)

# 2.2 选择sheet
sheet = workbook["Sheet1"]
print(sheet.max_row)  # 最大行号
print(sheet.max_column)  # 最大列号

# 2.3 我们选择了sheet后就可以去操作数据了
# cell = sheet.cell(1, 1)  # 获取到单元格
# print(cell.value)

sheet 相关操作

from openpyxl import load_workbook

# 1. 打开Excel文件 
workbook = load_workbook("p1.xlsx")
# 2. 选择sheet
# 2.1 获取所有sheet
# print(workbook.sheetnames)

# 2.2 选择sheet
# sheet = workbook["Sheet1"]
# 2.3 基于索引的方式获取sheet
# sheet = workbook.worksheets[0]
# 3. 获取到所有的sheet
# for name in workbook.sheetnames:
# 	sheet = workbook[name]
# 	cell = sheet.cell(1, 1)
# 	print(cell.value)

读单元格的数据

from openpyxl import load_workbook

# 1. 打开Excel文件 
workbook = load_workbook("p1.xlsx")
# 2 获取sheet
sheet = workbook.worksheets[0]

# 获取到第N行第N列的单元格
# cell = sheet.cell(1, 2)
# print(cell.value)

# 获取到某个单元格

# cell = sheet['A2']
# print(cell.value)

# print()
# for cell in sheet[1]:  # 获取到第一行的内容
# 	print(cell.value)


# 获取到所有的行的数据 获取到一列的值
# for row in sheet.rows:
# 	print(row[0].value)

# 获取到所有的列的数据 获取到一行的值
for col in sheet.columns:
	print(col[0].value)

# 1. 在原有的Excel的基础上写内容
# 2. 在一个新的Excel里面写内容

# from openpyxl import load_workbook
#
# # 1. 打开Excel文件
# workbook = load_workbook("p1.xlsx")
# # 2 获取sheet
# sheet = workbook.worksheets[0]
#
# # 获取到第N行第N列的单元格
# # cell = sheet.cell(1, 2)
# # print(cell.value)
#
# # 获取到某个单元格
#
# # cell = sheet['A2']
# # print(cell.value)
#
# # print()
# # for cell in sheet[1]:  # 获取到第一行的内容
# # 	print(cell.value)
#
#
# # 获取到所有的行的数据 获取到一列的值
# # for row in sheet.rows:
# # 	print(row[0].value)
#
# # 获取到所有的列的数据 获取到一行的值
# for col in sheet.columns:
# 	print(col[0].value)

# from openpyxl import workbook
# wb = workbook.Workbook()  # 创建一个Excel会默认有一个sheet 就叫	Sheet

# 1. 修改sheet名称
# sheet = wb.worksheets[0]
# sheet.title = '数据集'
# wb.save('p2.xlsx')

# 2. 创建一个新的sheet 还可以设置颜色
# sheet = wb.create_sheet('工作计划', 1)
# sheet.sheet_properties.tabColor = 'FFB6C1'
# wb.save('p2.xlsx')

# 3. copy sheet
# sheet = wb.create_sheet('工作计划')
# sheet.sheet_properties.tabColor = 'FFB6C1'
#
# new_sheet = wb.copy_worksheet(wb['Sheet'])
# new_sheet.title = '新的计划'
# wb.save('p2.xlsx')
# print(wb.sheetnames)
# sheet = wb.worksheets[0]
# cell = sheet.cell(1, 1)
# cell.value = '哈哈哈'
#
# wb.save('p2.xlsx')



from openpyxl import load_workbook

# 1. 打开Excel文件
workbook = load_workbook("p2.xlsx")
# 2 获取sheet
sheet = workbook.worksheets[0]
# 1. 获取某个单元格 修改值
# cell = sheet.cell(1, 1)
# cell.value = '哈哈哈'
# wb.save('p2.xlsx')
# 2. 获取某个单元格 修改值
# sheet['B3'] = '光'
# workbook.save('p2.xlsx')

# cell_list = sheet["B2": 'C3']
# for row in cell_list:
#     for cell in row:
#         cell.value = '新的值'
# workbook.save('p1.xlsx')


for row in sheet.iter_rows(min_row=5, min_col=1, max_col=7, max_row=10):
    for cell in row:
        cell.value = 'oo'
workbook.save('p1.xlsx')
