我正在尝试在 python 中使用 HTML img 标签发送邮件，但出现以下错误

Question

    import win32com.client as win32
    outlook = win32.Dispatch('outlook.application')
    mail = outlook.CreateItem(0)
    mail.To = 'abc@gmail.com'
    mail.Subject = 'Test Mail'
    mail.Body = 'Test'
    mail.HTMLBody = '''<img src="C:\Users\tkakati\Desktop\Automated mail\books_read.png" alt="Plot 1">''' #this field is optional
mail.Send()

I've been trying to run this code but I'm getting the following error:

(unicode error) 'unicodeescape' codec can't decode bytes in position 437-438: truncated \UXXXXXXXX escape

Answer 1

您需要转义src的单个\\ ，最简单的方法是使用字符串文字r

mail.HTMLBody = r'''<img src="C:\Users\tkakati\Desktop\Automated mail\books_read.png" alt="Plot 1">'''
