Operators in Python Explained for Pharmacy Students (With Dosage Calculations & Clinical Logic)
Operators in Python are used to perform operations on variables and values. In pharmaceutical applications, operators are essential for dose calculations, concentration adjustments, and clinical decision-making.
๐ท Types of Operators in Python
- Arithmetic Operators
- Comparison Operators
- Logical Operators
- Assignment Operators
๐ท Arithmetic Operators
Used for mathematical calculations.
| Operator | Symbol | Example |
|---|---|---|
| Addition | + | dose = 250 + 250 |
| Subtraction | – | remaining = 500 – 150 |
| Multiplication | * | total = dose * days |
| Division | / | conc = 500 / 100 |
๐ Dosage Calculation Example
dose_per_kg = 10 weight = 60 total_dose = dose_per_kg * weight print(total_dose)
This calculates total dose based on patient weight.
๐ท Comparison Operators
Used to compare values.
| Operator | Meaning |
|---|---|
| == | Equal to |
| != | Not equal to |
| > | Greater than |
| < | Less than |
๐ Clinical Condition Example
temperature = 102
if temperature > 100:
print("Fever detected")
๐ท Logical Operators
Used to combine conditions.
| Operator | Meaning |
|---|---|
| and | Both conditions true |
| or | At least one condition true |
| not | Reverses condition |
๐ Drug Safety Check
age = 65
has_kidney_issue = True
if age > 60 and has_kidney_issue:
print("Adjust dose")
๐ท Assignment Operators
Used to assign values.
dose = 500 dose += 100 # dose = dose + 100

๐งช Practice Exercise
weight = 70 dose_per_kg = 5 total = weight * dose_per_kg print(total)
