代码1：logical_invert()方法示例

# Python Program explaining  
# logical_invert() method 
  
# loading decimal library 
from decimal import *
  
  
# Initializing a decimal value 
a = Decimal('0') 
  
b = Decimal('1') 
  
# printing Decimal values 
print ("Decimal value a : ", a) 
print ("Decimal value b : ", b) 
  
  
# Using Decimal.logical_invert() method 
print ("\n\nDecimal a with logical_invert() method : ", a.logical_invert()) 
  
print ("Decimal b with logical_invert() method : ", b.logical_invert())

输出：

Decimal value a :  0
Decimal value b :  1


Decimal a with logical_invert() method :  1111111111111111111111111111
Decimal b with logical_invert() method :  1111111111111111111111111110

代码2：logical_invert()方法的示例

# Python Program explaining  
# logical_invert() method 
  
# loading decimal library 
from decimal import *
  
  
# Initializing a decimal value 
a = Decimal('1') 
  
b = Decimal('0') 
  
# printing Decimal values 
print ("Decimal value a : ", a) 
print ("Decimal value b : ", b) 
  
  
# Using Decimal.logical_invert() method 
print ("\n\nDecimal a with logical_invert() method : ", a.logical_invert()) 
  
print ("Decimal b with logical_invert() method : ", a.logical_invert())

输出：

Decimal value a :  1
Decimal value b :  0


Decimal a with logical_invert() method :  1111111111111111111111111110
Decimal b with logical_invert() method :  1111111111111111111111111110
