《笨办法学python》第3课手记
本节课介绍运算符,如果你有C语言的基础的话很简单,运算符跟C语言都一样,优先级也一样。出现小数会四舍五入。但逻辑判断时,C语言返回0或1,python直接返回False和True。
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 ture 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>=-2-1/4
print "Is it less or equal", 5<=-2
结果:
有空行的地方会自动换行。
行与行之间没有空行输出结果会直接跟在后面。
