조건문(Conditional Statements)

"if" 조건문

def evaluate_temp(temp):
    # Set an initial message
    message = "Normal temperature."
    # Update value of message only if temperature greater than 38
    if temp > 38:
        message = "Fever!"
    return message

print(evaluate_temp(37))

결과: Normal temperature.

 

print(evaluate_temp(39))

결과: Fever!

 

"if ... else" 조건문

def evaluate_temp_with_else(temp):
    if temp > 38:
        message = "Fever!"
    else:
        message = "Normal temperature."
    return message

print(evaluate_temp_with_else(37))

결과: Normal temperature.

 

"if ... elif ... else" 조건문

def evaluate_temp_with_elif(temp):
    if temp > 38:
        message = "Fever!"
    elif temp > 35:
        message = "Normal temperature."
    else:
        message = "Low temperature."
    return message

evaluate_temp_with_elif(36)
