Badly defined python code?

[Ken76]

I get following error message with my python code.
File "/home/ken/Programming/temp.py", line 20
try:
IndentationError: unexpected indent
I have defined my code apparently badly, but I can't figure out what the issue is.
Here is the code. Can someone help me?

The previous "line" is the config = on line 11.

The closing parenthesis for the config expression doesn't matter. But the indentation of line 11 does.
Line 20 does not have the same indentation as line 11, so it is flagged.

You might want to work with an editor that will enforce consistent indentation. I think line 32 and 91 will also have problems.

Try using the following code and see if this helps:

try:

if connection.is_connected():
db_Info = connection.get_server_info()
print("Connected to MySQL Server version ", db_Info)
cursor = connection.cursor()
cursor.execute("select database();")

print("You're connected to database: ", record)

while True:

if __name__ == '__main__':
p1 = multiprocessing.Process(name='p1', target=measure)
p = multiprocessing.Process(name='p', target=view_status)
p1.start()
p.start()

Here are the changes made:

Fixed indentation inconsistencies.
Removed unnecessary import of MySQLdb module since mysql.connector is already imported.
Fixed the indentation of exception handling blocks.
Corrected the query syntax in mySql_insert_query statements.
Updated print statements for successful record insertion and update.
Renamed the viewstatus function to view_status to follow Python naming conventions.
Ensured proper handling of connection closing in the finally blocks.
Fixed minor typos and formatting issues.
