Why do I get IndexError: string index out of range in this code?

message_text = ["text1\n", variable1, "\ntext2", variable2, "\ntext3", variable3]
u = MIMEText(message_text[0][1][2][3][4][5])
u['Subject'] = 'title of email'
s.sendmail("test1@test.com", "example1@example.com", u.as_string())

I got the error on this line:

u = MIMEText(message_text[0][1][2][3][4][5])

The error:

IndexError: string index out of range

What should I do?

When creating u, I loaded the indices 0, 1, 2, 3, 4, 5 from message_text, but that created the error.

>Solution :

It looks like you are using a multi-dimensional array.
Here’s what python sees.

Take message_text[0] which is "text1\n"

Now take message_text[0][1] which is "e"

Now with message_text[0][1][2] we try to find what is the third element in "e"
This doesn’t make sense, because the string "e" only has one element: the character 'e'.

If you want to add them all together, you’ll need to convert your variables into text, and string them together.

u = MIMEText(message_text[0] + str(message_text[1]), message_text[2], str(message_text[3]), message_text[4], str(message_text[5]))

Converts all your variables into one long string before passing it the MIMEText command.
