python-赋值变量符

1. python-赋值变量符

• 赋值操作变量

  操作符	描述	示例
  =	赋值，将=左侧的结果赋值给等号左侧的变量	a = 10 b = 20
  +=	加法赋值	c += a 等价c = c + a
  -=	减法赋值	c -= a 等价c = c –a
  *=	乘法赋值	c *= a 等价c = c * a
  /=	除法赋值	c /= a 等价c = c / a
  //=	整除赋值	c //= a 等价c = c // a
  %=	取余赋值	c %= a 等价c= c % a
  **=	幂赋值	c = a 等价c = c a

  a = 10
  b = 20
  
  c = a + b                   # c等于 10+20=30
  
  c += a                     # c = 10+30
  
  print(c)
