Program Flow Control
-
Conditional Statements:
-
if: Executes a block if a condition is true. -
elif: Checks another condition if the previous ones were false. -
else: Executes a block if all previous conditions were false.
-
-
Loops:
-
For Loop: Iterates over a sequence (e.g., list, tuple, string).
- Syntax:
for item in sequence:
- Syntax:
-
While Loop: Repeats as long as a condition is true.
- Syntax:
while condition:
- Syntax:
-
For Loop: Iterates over a sequence (e.g., list, tuple, string).
-
Control Statements:
-
break: Exits the current loop. -
continue: Skips the current iteration and continues with the next. -
pass: A null statement that does nothing; used as a placeholder.
-
Lists
-
Definition: An ordered, mutable collection of items.
-
Characteristics:
- Can contain mixed data types.
- Defined using square brackets:
my_list = [1, 2, 3].
-
Common Methods:
-
append(): Adds an item to the end. -
remove(): Removes the first occurrence of an item. -
pop(): Removes and returns an item at a given index. -
sort(): Sorts the list in ascending order.
-
-
List Comprehensions: A concise way to create lists.
- Syntax:
[expression for item in iterable if condition].
- Syntax:
Tuples
-
Definition: An ordered, immutable collection of items.
-
Characteristics:
- Defined using parentheses:
my_tuple = (1, 2, 3). - Cannot be modified after creation.
- Defined using parentheses:
-
Usage:
- Ideal for fixed collections of items.
- Can contain mixed data types.
-
Common Methods:
-
count(): Returns the number of occurrences of a value. -
index(): Returns the index of the first occurrence of a value.

- A tool that categorizes tasks into four quadrants based on urgency and importance, aiding in prioritization.
-
Pomodoro Technique:
- Involves working in 25-minute intervals followed by a 5-minute break, enhancing concentration and productivity through structured time management.
-
SMART Goals:
- Framework to set goals that are Specific, Measurable, Achievable, Relevant, and Time-bound, ensuring clarity in objectives.
Common Challenges
-
Procrastination:
- A tendency to delay tasks, causing stress and last-minute pressure.
-
Overcommitment:
- Taking on too many responsibilities can lead to decreased productivity and overwhelm.
-
Distractions:
- Recognizing and managing interruptions is vital for maintaining focus on tasks.
