Study Notes
Conditional Statements in Python
- Conditional statements allow code execution based on true or false conditions.
- The main conditional statements in Python are
if
,elif
, andelse
.
if Statement
- Used to test a specific condition.
- Executes the code block if the condition evaluates to True.
-
Syntax:
if condition: # code to execute if condition is true
-
Example:
x = 10 if x > 5: print("x is greater than 5")
- Output: "x is greater than 5" since 10 is greater than 5.
else Statement
- Follows an
if
statement and executes if theif
condition is False. -
Syntax:
if condition: # code to execute if condition is true else: # code to execute if condition is false
-
Example:
x = 2 if x > 5: print("x is greater than 5") else: print("x is not greater than 5")
- Output: "x is not greater than 5" since 2 is not greater than 5.
elif Statement
- Stands for "else if" and allows checking multiple conditions.
- Must follow an
if
and precede anelse
. -
Syntax:
if condition1: # code to execute if condition1 is true elif condition2: # code to execute if condition2 is true else: # code to execute if neither condition is true
-
Example:
x = 7 if x > 10: print("x is greater than 10") elif x > 5: print("x is greater than 5 but less than or equal to 10") else: print("x is 5 or less")
- Output: "x is greater than 5 but less than or equal to 10" since 7 is greater than 5 but less than 10.
Nested Conditional Statements
- Conditional statements can be nested within one another to evaluate multiple conditions simultaneously.
