    <p>Yes,you should take a look at this question <a href="https://stackoverflow.com/questions/423379/using-global-variables-in-a-function-other-than-the-one-that-created-them">Using global variables in a function other than the one that created them</a></p> <p>Briefly speaking,if it is only reading from a name, and the name doesn't exist locally, it will try to look up the name in any containing scopes.That's what happens to <code>temp</code>,which will be found in the global scope.But with <code>hhh</code>,you do writing,which will make Python believe that <code>hhh</code> is a local variable. </p> <p>And another thing,but more important,it is not recomended using <code>global</code>.You could invoke <code>actualcrawl()</code> in <code>start()</code>,and pass in <code>hhh,temp</code>,which is the way most people do.</p> <p>EDIT</p> <p>It is simple:</p> <pre><code>import random,os def start(): level=1 temp=' +-!' hhh='[X' os.system('CLS') actualcrawl(temp,hhh) def actualcrawl(temp,hhh): print (temp) for a in range(2,128): hhh=hhh+temp[random.randrange(1,8)] hhh=hhh[:79]+'&gt;'+hhh[80:] for i in range(1,3): a=random.randrange(3,8) b=random.randrange(6,15) hhh=hhh[:16*a+b-1]+'='+hhh[16*a+b:] for i in range(1,9): print (hhh[16*i-16:16*i]) </code></pre> <p>I don't know what language you use before Python,but you really don't need to declare a variable like in C/C++.Because when you assign to a variable, you are just binding the name to an object.See this <a href="https://stackoverflow.com/questions/13530998/python-variables-are-pointers">python variables are pointers?</a></p>

    1. COI have been programming in python for 2 days now and have no idea how to pass variables. How would one go about doing something like that?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
