第3个练习主要说明在python中数学符号的用法,编辑器中输入以下代码:
print("I will now count my chickens:")
print("Hens",25+30/6)
print("Roosters",100-25*3%4)
print("Now I will count the eggs:")
print(3+2+1-5+4%2-1/4+6)
print("Is it true that 3+2 < 5-7?")
print(3+2<5-7)
print("what is 3+2?",3+2)
print("what is 5-7?",5-7)
print("Oh, that's why it's False.")
print("How about some more.")
print("Is it greater?", 5>-2)
print("Is it greater or equal?",5>=-2)
print("Is it less or equal?",5<=-2)
运行后将得到:
