工程师经常要在Excel表格上进行增删修改操作,打开Excel软件输入数据,费时费力,那有没有一种方法无需打开Excel软件,能快速输入数据,当然有!
1、Python写Excel
Python写Excel操作需要用到xlwt模块。
import xlwt#设置表格样式
def set_style(name,height,bold=False):
style = xlwt.XFStyle()
font = xlwt.Font()
font.name = name
font.bold = bold
font.color_index = 4
font.height = height
style.font = font
return style#写Exceldef write_excel():
f = xlwt.Workbook()
sheet1 = f.add_sheet('学生',cell_overwrite_ok=True) row0 = ["姓名","年龄","出生日期","爱好"]
colum0 = ["张三","李四","恋习Python","小明","小红","无名"] #写第一行
for i in range(0,len(row0)):
sheet1.write(0,i,row0[i],set_style('Times New Roman',220,True))
#写第一列 for i in range(0,len(colum0)): sheet1.write(i+1,0,colum0[i],set_style('Times New Roman',220,True))
sheet1.write(1,3,'2006/12/12')
sheet1.write_merge(6,6,1,3,'未知')#合并行单元格 sheet1.write_merge(1,2,3,3,'打游戏')#合并列单元格 sheet1.write_merge(4,5,3,3,'打篮球')
f.save('test.xls')if __name__ == '__main__': write_excel()
结果如图所示:
2、Python读Excel
我们要使用Python读取Excel软件的数据,可通过xlrd,具体例子如下:
import xlrdfrom datetime
import date,datetimefile = 'test3.xlsx'def read_excel():
wb = xlrd.open_workbook(filename=file)#打开文件 print(wb.sheet_names())#获取所有表格名字
sheet1 = wb.sheet_by_index(0)#通过索引获取表格 sheet2 = wb.sheet_by_name('年级')#通过名字获取表格 print(sheet1,sheet2)
print(sheet1.name,sheet1.nrows,sheet1.ncols)
rows = sheet1.row_values(2)#获取行内容
cols = sheet1.col_values(3)#获取列内容
print(rows)
print(cols)
print(sheet1.cell(1,0).value)#获取表格里的内容,三种方式
print(sheet1.cell_value(1,0))
print(sheet1.row(1)[0].value)
