python用openpyxl读写Excel

pip3 install openpyxl

from openpyxl import Workbook

#创建Workbook，并默认会创建一个空表,名称为：Sheet
wb = Workbook()
#获取默认的sheet
ws1 = wb.active
#设置Sheet名称
ws1.title = 'Sheet1'
#写入单个单元格
ws1['A1'] = '标题列1'
ws1['B1'] = '标题列2'
#写入多个单元格(从有数据的行的下一行写入)
ws1.append(['张三', 80])
ws1.append(['李四', 90])

#创建一个新sheet，可以指定名称
ws2 = wb.create_sheet('Sheet2')

#复制Sheet1，新sheet名称为Sheet1 Copy
ws3 = wb.copy_worksheet(wb['Sheet1'])

#打印所有表名
print(wb.sheetnames)

#保存
wb.save('1.xlsx')

from openpyxl import Workbook
from openpyxl import load_workbook

wb = load_workbook('1.xlsx')
#猜测格式类型
wb.guess_types = True   
ws1 = wb.active

print('总行数', ws1.max_row)
print('总列数', ws1.max_column)

print('---获取单个单元格的值---')
print(ws1['A1'].value)
print(ws1[1][0].value) #这里也是A1值,行索引从1、列索引从0算起

print('---获取单列的所有值---')
for cell in ws1['A']:
    print(cell.value)

print('---获取多列的值(通过切片)---')
#如果范围比实际大，如实际只有AB两列，指定A:B，则获取结果返回None，并且C列会被后面.columns和.rows获取到
for column in ws1['A:B']:
    for cell in column:        
        print(cell.value)

print('---获取所有列的值---')
for column in ws1.columns: #也可用ws1.iter_cols()
    for cell in column:
        print(cell.value)

print('---获取某行的值---')
for cell in ws1[1]:
    print(cell.value)

print('---获取多行的值(通过切片)---')
for row in ws1[1:2]:
    for cell in row:
        print(cell.value)

print('---获取所有行的值---')
for row in ws1.rows: #也可用ws1.iter_rows()
    for cell in row:
        print(cell.value)
