Python 1-07 conditions and loop statements

One, conditional statement

1, if <condition>:

age = int(input('Please enter your age:'))

if age >= 18:
    print(f' Your age is { age } , and you are an adult with Internet access.')
else:
    print(f'Your age is { age } , please go home and do your homework.')

2. Multiple judgments

score = int(input('Please enter your scores:'))
if score < 60:
    print(f'Your score is a {score}, grade is "E" .')  
elif (score < 70):
	print(f'Your score is a {score}, grade is "D" .')  
elif (score < 80):
	print(f'Your score is a {score}, grade is "C" .')  
elif (score < 90):
	print(f'Your score is a {score}, grade is "B" .')  
else:
	print(f'Your score is a {score}, grade is "A" .')  

Python does not have a switch statement and can be implemented using multiple conditional statements.

3. Ternary operator
