Data Types — definition?
Categories of data that determine stored values.
Variables — role?
Store data values during program execution.
Type Casting — mechanism?
Converts data from one type to another.
Operators — symbols?
Perform operations on variables and values.
Arithmetic Expressions — purpose?
Evaluate to a single numerical value.
Escape Sequences — use?
Insert special characters in strings.
Escape Sequence — example?
` ` for newline.
Variables — dynamic?
Yes, their data types can change.
Input Function — returns?
User input as a string.
Assignment Statement — syntax?
`variable = value`.
Operator Precedence — effect?
Determines evaluation order in expressions.
Type Casting — explicit?
Manual conversion using functions like `int()`, `float()`.
Comments — start with?
`#` in Python.
Running Scripts — methods?
IDLE, terminal, REPL.
Built-In Functions — examples?
`print()`, `input()`, `type()`.
User Modules — purpose?
Organize and reuse code.
NumPy Array — core type?
ndarray, multi-dimensional, efficient.
Array Creation — functions?
`np.array()`, `np.zeros()`, `np.ones()`.
DataFrame — structure?
Tabular data with labeled axes.
DataFrame — created from?
Dictionaries, lists, external files.
NumPy Arrays — advantage?
Fast, memory-efficient numerical computations.
Pandas DataFrames — key feature?
Labeled, flexible tabular data structure.
Escape sequences — include?
` `, ` `, `\`, `"`, `rd.
Variables — assign?
Using `=` operator.
