假設變數 a=10 和 變數b=20，然後：
| 操作符 | 描述 | 示例 |
|---|---|---|
| + |
將操作符的兩側數值增加(加法運算)
|
a + b = 30 |
| - |
左運算元減去右運算元
|
a – b = -10 |
| * |
操作符兩側數據相乘(乘法運算)
|
a * b = 200 |
| / |
操作符左側運算元除以右運算元
|
b / a = 2 |
| % |
左運算元除以右側運算元的餘數
|
b % a = 0 |
| ** |
執行指數(冪)計算
|
a**b 就是10 的20 次冪 |
| // | 地板除 - 除法不管運算元為何種數值類型，總是會舍去小數部分，返回數字序列中比真正的商小的最接近的數字 | 9//2 = 4 以及 9.0//2.0 = 4.0 |
示例
假設變數 a = 10和變數 b = 20，那麼 -
#!/usr/bin/python3
a = 21
b = 10
c = 0
c = a + b
print ("Line 1 - Value of c is ", c)
c = a - b
print ("Line 2 - Value of c is ", c )
c = a * b
print ("Line 3 - Value of c is ", c)
c = a / b
print ("Line 4 - Value of c is ", c )
c = a % b
print ("Line 5 - Value of c is ", c)
a = 2
b = 3
c = a**b
print ("Line 6 - Value of c is ", c)
a = 10
b = 5
c = a//b
print ("Line 7 - Value of c is ", c)
當你執行上面的程式，它會產生以下結果 -
Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2.1 Line 5 - Value of c is 1 Line 6 - Value of c is 8 Line 7 - Value of c is 2
