I'm running into this issue when using mySQL. My result = [{'email': 'bernie@shrimp.com'}] but I'm getting an TypeError: tuple indices must be integers or slices, not str when I'm doing email = results[0]['email']

The thing is when I'm running this locally it works perfectly. How do I get bernie@shrimp.com?

users is a table

Code:

cursor.execute('SELECT email FROM users WHERE username = %s', [attempted_username])
email_dict = cursor.fetchall()
print(email_dict)
session['email'] = email_dict[0]['email']

Console: 

[{'email': 'bernie@shrimp.com'}]
pythonanywhere mysql python

The result of fetchall is a list of tuples, not a list of dict.

Your query result have only one field: email at index 0.

You can rewrite your code like this:

rows = cursor.fetchall()
for row in rows:
    email = row[0]

Or, in your situation where there is only one result:

session['email'] = rows[0][0]

I think, you can also use:

row = cursor.one()
user_15139330

fetchall returns a list of tupples. You need to access it by the column's ordinal, not its name:

session['email'] = email_dict[0][0]
user_24227760
