Python Code Example: multi-branches
In Python there are also multiple branches represented by the elif statement
The if-conditions are evaluated in sequence until one of them is true. Then finally the code section belonging to this condition is executed and the multiple branching handling is finished. The else-part is only executed if none of the conditions is true.
| Line | Description |
|---|---|
| 1 | Prompts the user to enter a number. This is stored in the variable firstNumber |
| 2 | Prompts the user to enter a number. This is stored in the variable secondNumber |
| 4 – 5 | If the value of the variable firstNumber is greater than the value of the variable secondNumber, the string “value_first_variable > value_second_variable” is output |
| 6 – 7 | If firstNumber is smaller than secondNumber, the string “value_first_variable < value_second_variable” is output |
| 8 – 9 | Otherwise the string “value_first_variable = value_second_variable” is output |
firstNumber = input("Please enter first number: ")
secondNumber = input("Please enter second number: ")
if (firstNumber > secondNumber):
print(firstNumber + " > " + secondNumber)
elif (firstNumber < secondNumber):
print(firstNumber + " < " + secondNumber)
else:
print(firstNumber + " = " + secondNumber)Output
Please enter first number: 5
Please enter second number: 8
5 < 8
