Where should I put rollback?

A transaction must end with either a rollback () or commit () (only one of them) < / P>

It is usually executed only one with a if ... and statement Or go to.

dbConnect-> gt; Startbank (); // somecode // $ dbConnect-> execute ($ some INnsert); // some more code // $ Result = $ dbConnect-> Execute ($ some selection); // $ nextRow = $ result- & gt; receive cry (); // either committed or rollback! If ($ some result check == True) $ dbConnect-> Comment (); and $ dbConnect->; Rollback ();

< P>

A transaction is usually a complex argument associated with the question, then it is used.

If you are using MySQL, make sure that you do not use the MyISAM engine for tables because it does not support transactions.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
