总结Python中逻辑运算符的使用

这个小城,步入冬天就立马变了颜色,还没来得及等我换件衣服就开演了。如何扮演好自己的角色,我还没想好,我不适合做主角,只能在配角方面下功夫,极力配合主角旦,生的表演。红红火火的演完这场戏,让北方的冬天刮目相看。

下表列出了所有Python语言支持的逻辑运算符。假设变量a持有10和变量b持有20,则:

示例:

试试下面的例子就明白了所有的Python编程语言提供了逻辑运算符:

#!/usr/bin/python

a = 10
b = 20
c = 0

if ( a and b ):
  print "Line 1 - a and b are true"
else:
  print "Line 1 - Either a is not true or b is not true"

if ( a or b ):
  print "Line 2 - Either a is true or b is true or both are true"
else:
  print "Line 2 - Neither a is true nor b is true"


a = 0
if ( a and b ):
  print "Line 3 - a and b are true"
else:
  print "Line 3 - Either a is not true or b is not true"

if ( a or b ):
  print "Line 4 - Either a is true or b is true or both are true"
else:
  print "Line 4 - Neither a is true nor b is true"

if not( a and b ):
  print "Line 5 - Either a is not true or b is not true"
else:
  print "Line 5 - a and b are true"

当执行上面的程序它会产生以下结果:

Line 1 - a and b are true
Line 2 - Either a is true or b is true or both are true
Line 3 - Either a is not true or b is not true
Line 4 - Either a is true or b is true or both are true
Line 5 - Either a is not true or b is not true

以上就是总结Python中逻辑运算符的使用。别老想着取悦别人,你越在乎别人,就越卑微。只有提升自己,取悦自己,并让别人来取悦你,才会令你更有价值。一辈子不长,记住:对自己好点。早安!更多关于总结Python中逻辑运算符的使用请关注haodaima.com其它相关文章!
