10月18日学习总结

一、办公自动化：Excel文件读取

from datetime import datetime

import openpyxl
from openpyxl.cell.cell import Cell
from openpyxl.chart import Reference, LineChart
from openpyxl.styles import Alignment, Font, Border, Side
from openpyxl.worksheet.worksheet import Worksheet


def display(value, delim=' '):
    if isinstance(value, float):
        print(f'{value:>10.2f}', end=delim)  # 右对齐，保留10位宽度
    elif isinstance(value, datetime):
        print(value.strftime('%Y年%m月%d日'), end=delim)
    elif isinstance(value, int):
        print(f'{value:>10d}', end=delim)
    else:
        print(value, end=delim)

1. 获取工作簿

workbook = openpyxl.load_workbook('resources/阿里巴巴2020年股票数据.xlsx')

2. 获取工作表

# sheet = workbook.active

# 获取所有的工作表workbook.worksheets
for sheet in workbook.worksheets:
    print(sheet.title)

# 通过下标获取工作表
sheet = workbook.worksheets[0]
print(sheet.title)

# 通过工作表名获取工作表（如果没有提示，可以在后面注释变量类型）
sheet = workbook['股票数据']

3. 获取工作表的属性

print(sheet.max_row, sheet.max_column)
print(sheet.dimensions)

4. 操作单元格

cell = sheet['E5']  # type: Cell
# cell = sheet.cell(5, 5)
print(cell.value)

# 修改单元格内容
cell.value = 200
sheet['E5'] = 200
sheet.cell(5, 5, 200)

5. 遍历循环所有单元格

for row in range(1, sheet.max_row + 1):
    for col in range(1, sheet.max_column + 1):
        display(sheet.cell(row, col).value)
    print()

6. 公式计算

sheet['E256'] = '=average(e2:e255)'
sheet['F256'] = '=sum(f2:f255)'

7. 设置格式

cell = sheet['E256']
cell.value = '我爱你中国'
# 对齐方式
cell.alignment = Alignment(horizontal='center', vertical='center')

# 字体
cell.font = Font(name='微软雅黑', size=20, color='330099')

# 边框
side = Side(color='ff6600', style='mediumDashed')
cell.border = Border(left=side, right=side, top=side, bottom=side)

# 行高和列宽
sheet.row_dimensions[256].height = 50
sheet.column_dimensions['E'].width = 35

8. 绘制图表

c1 = LineChart()
c1.title = '一月份收盘价和开盘价'
c1.style = 13
c1.y_axis.title = '价格'
c1.x_axis.title = '日期'

# 添加数据引用（纵轴）
data = Reference(sheet, min_col=4, min_row=1, max_row=23)
c1.add_data(data, titles_from_data=True)

# 设置数据类别（横轴）
cats = Reference(sheet, min_col=1, min_row=2, max_row=23)
c1.set_categories(cats)

# 给数据序列设置样式
s1 = c1.series[0]
s1.marker.symbol = "triangle"
s1.marker.graphicalProperties.solidFill = "ff0000"
s1.marker.graphicalProperties.line.solidFill = "0000ff"
s1.smooth = True

# 将图表添加到工作表中
sheet.add_chart(c1, "A258")

9. 保存工作簿

workbook.save('resources/阿里巴巴2020年股票数据.xlsx')

二. Python发送邮件

创建SMTT_SSL对象

1.登录授权

2.发送邮件

3.结束会话

# 发送文本
import smtplib
from email.mime.text import MIMEText

# 创建SMTP_SSL对象
smtp_obj = smtplib.SMTP_SSL(host='smtp.163.com',port=465)
# 1.登录授权
smtp_obj.login('wby5135124@163.com','YYKOSUNNXKELSUVP')

content="""天气预报说：明天有暴雨。所以如果明天A计划失败，咱们就执行B计划"""
mime_text = MIMEText(content,'plain','utf-8')
mime_text['From'] = 'wby5135124@163.com'
mime_text['To'] = '1735651388@qq.com'
mime_text['Subject'] = '秘密行动'

# 2.发送邮件
smtp_obj.sendmail(
    from_addr='wby5135124@163.com',
    to_addrs=['1735651388@qq.com'],
    msg=mime_text.as_string()
)

# 3.结束会话
smtp_obj.quit()
