Python Coding Conventions

• Indentation is 4 spaces.  Always.
• Variable names and function/method names start with lower-case letters. Then, use camelCase. I.e., subsequent words in the variable name are capitalized. 
• Make variable names meaningful, but hopefully not too long.
• Use comments where appropriate to explain a tricky line of code, or to explain a block of code coming up.  Prefer comments on their own line instead of comments to the right of code.
• Keep lines short -- 79 characters or less is best.  This is not a hard and fast rule, but something to strive for.
• Use a space around operators: e.g.,

• Don't put a space before the left parenthesis in a method/function call:
  
  Good:   result = sqrt(x)      Bad:  result = sqrt (x)
