    <p>So i am making a program to draw specific letters using turtle and I have set up a parameter scale to effect the size and pen thickness of the program based on a prompt to input. here is what I have... I keep getting an error saying scale is not defined.</p> <pre><code>import turtle def drawLetter( letter ): if letter == " ": space(scale) elif letter == "i": i_lc(scale) elif letter == "I": i_uc(scale) elif letter == "s": s_lc(scale) elif letter == "S": s_uc(scale) elif letter == "C": c_uc(scale) elif letter == "c": c_lc(scale) def space(scale): turtle.up() turtle.forward( 30 * scale ) def questionMark(): """ Draw a question mark.

    1. COMake this post more readable by formatting your code correctly and limiting the amount of code you put in (only show what's necessary to demonstrate and reproduce the error). Far as I understand you call `c_lc(scale)` (for example) but you do not define a variable called `scale` in the "top" program which prints the letters. Hence the error.

    2. COPlease, do *not* use tabs to indent. You should use 4 spaces instead of a tab. **Any** editor has an option to insert spaces instead of tab when pressing the tab key, so no excuses for this. (About why to avoid tabs: they look different in different environments, so even if in your computer the code looks right, in another the indents may be cluttered. Also when copy-pasting from website I often have problems of mixed space and tabs)

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.
