16 Conditional Operators
- 可以製作出True/False結果的operations有很多，這邊整理一下：
16.0.1 ==, !=, >=, <=
這些operator，我們稱為comparison operators，適用於數值型資料：
比大小：
a == b,a != b,a < b,a <= b,a > b,a >=b餘數類：
a % 3 == 0只想看商：
a // 3 == 1
a = 33
b = 200
if b > a:
print("b is greater than a")
#> b is greater than a
16.0.2 and, or, not
- 這種operator，我們稱為logical operators，適用於連接多個condition
- logical operators就是
and,or,not，對應到R的&,|,!
a = 200
b = 33
c = 500
if a > b and c > a:
print("Both conditions are True")
#> Both conditions are True
if a > b or a > c:
print("At least one of the conditions is True")
#> At least one of the conditions is True
if not(b > a):
print("a is greater or equal to b")
#> a is greater or equal to b
