假設變數a的值10，變數b的值是21，則 -
| 運算子 | 描述 | 範例 |
|---|---|---|
= |
將右側運算元的值分配給左側運算元 | c = a + b表示將a + b的值分配給c |
+= |
將右運算元相加到左運算元，並將結果分配給左運算元 | c + = a等價於c = c + a |
-= |
從左運算元中減去右運算元，並將結果分配給左運算元 | c -= a 等價於 c = c - a |
*= |
將右運算元與左運算元相乘，並將結果分配給左運算元 | c *= a 等價於 c = c * a |
/= |
將左運算元除以右運算元，並將結果分配給左運算元 | c /= a 等價於 c = c / a |
%= |
將左運算元除以右運算元的模數，並將結果分配給左運算元 | c %= a 等價於 c = c % a |
**= |
執行指數(冪)計算，並將值分配給左運算元 | c **= a 等價於 c = c ** a |
//= |
運算子執行地板除運算，並將值分配給左運算元 | c //= a 等價於 c = c // a |
假設變數a的值是10，變數b的值是21，參考以下程式碼實現 -
#!/usr/bin/python3
#coding=utf-8
#save file : assignment_operators_example.py
a = 21
b = 10
c = 0
c = a + b
print ("Line 1 - Value of c is ", c)
c += a
print ("Line 2 - Value of c is ", c )
c *= a
print ("Line 3 - Value of c is ", c )
c /= a
print ("Line 4 - Value of c is ", c )
c = 2
c %= a
print ("Line 5 - Value of c is ", c)
c **= a
print ("Line 6 - Value of c is ", c)
c //= a
print ("Line 7 - Value of c is ", c)
將上面程式碼儲存到檔案： comparison_operators_example.py 中，執行結果如下 -
F:\worksp\python>python assignment_operators_example.py
Line 1 - Value of c is 31
Line 2 - Value of c is 52
Line 3 - Value of c is 1092
Line 4 - Value of c is 52.0
Line 5 - Value of c is 2
Line 6 - Value of c is 2097152
Line 7 - Value of c is 99864
