Python-openpyxl操作

from openpyxl import Workbook
from openpyxl import load_workbook
# 加载workbook，注意，openpyxl只支持xlsx格式
wb = load_workbook(filename=r"C:\\Users\\Administrator\\Desktop\\test.xlsx")

'''读取数据'''
num = wb.get_named_ranges
print(num)
# 获取每个sheet的名称
sheetnames = wb.get_sheet_names()
print(sheetnames)
# 获得第一个sheet
ws = wb.get_sheet_by_name(sheetnames[0])
print(ws)

ws = wb.active
# 写数据 第一种方式
ws['A4'] = 123
# 第二种方式
ws.cell(row=2, column= 3).value = 'bobo'

# 获取一个单元格的数据
c = ws['A4'].value
c2 = ws.cell(row= 2,column= 2).value
print(c,c2)
c3 = ws.cell(row=2, column=3).value
print(c3)

# 一次获取多个单元格的数据
cell_range = ws['A1':'B2']

cell_range2 = tuple(ws.iter_rows('A1:B2')) python3 有警告
for cell in cell_range:
print(cell)
for each_cell in cell:
print(each_cell.value)
# 保存写进去的数据
wb.save("C:\\Users\\Administrator\\Desktop\\test.xlsx")
