# (Part II) Python Fundamentals

💻 Topics the next two weeks:

I. Syntax and **readability** (snake_case, indentation, best naming conventions, key words)
II. More on loops
III. More on functions

Note:
- We're ignoring packages and array methods for a little while

### Variables
- scope
- naming

#### Naming


Different cases and when to use them:

(Differences between, and usages of, snake case, camelcase and all-caps camelcase in Python)

A few standard rules:

- Constants should be represented by all capital letters and separated by underscores when needed
- Use names that are representative of the meaning of the object rather than meaningless, single-character names
- Names i, j, and k should be reserved for representing index values

### Loops

- for loops
- while loops
