python operator - the most commonly used comparison operator in programming (example analysis)
Today in this article we will talk about Python comparison operators. There are seven different operators in total, namely equal to, not equal to, greater than, less than, greater than or equal to, and less than or equal to. These seven are more commonly used. Comparison operators. This is something that will be frequently used in future programming. I hope this article can help you reading.
Comparison operator: Comparison operator, as the name suggests, is an operation symbol used for comparison.
The following assumes that variable a is 10 and variable b is 20:
== 等于 - 比较对象是否相等 (a == b) 返回 False。 != 不等于 - 比较两个对象是否不相等 (a != b) 返回 true. <> 不等于 - 比较两个对象是否不相等 (a <> b) 返回 true。这个运算符类似 != 。 > 大于 - 返回x是否大于y (a > b) 返回 False。 < 小于 - 返回x是否小于y。所有比较运算符返回1表示真,返回0表示假。这分别与特殊的变量True和False等价。 (a < b) 返回 true。 >= 大于等于- 返回x是否大于等于y。 (a >= b) 返回 False。 <= 小于等于 -返回x是否小于等于y。 (a <= b) 返回 true。
It can be seen from the above symbols that comparison operators are not difficult. Here is an example:
#!/usr/bin/python# -*- coding: UTF-8 -*- a = 15 b = 9 c = 0 if (a == b): print "1 - a 等于 b" else: print "1 - a 不等于 b" if (a != b): print "2 - a 不等于 b" else: print "2 - a 等于 b" if (a <> b): print "3 - a 不等于 b" else: print "3 - a 等于 b" if (a < b): print "4 - a 小于 b" else: print "4 - a 大于等于 b" if (a > b): print "5 - a 大于 b" else: print "5 - a 小于等于 b" # 修改变量 a 和 b 的值 a = 5 b = 20 if (a <= b): print "6 - a 小于等于 b" else: print "6 - a 大于 b" if (b >= a): print "7 - b 大于等于 a" else: print "7 - b 小于 a"
The answer obtained from the above example is:
1 - c 的值为: 45 2 - c 的值为: -15 3 - c 的值为: 450 4 - c 的值为: 0 5 - c 的值为: 15 6 - c 的值为: 8 7 - c 的值为: 2 1 - a 不等于 b 2 - a 不等于 b 3 - a 不等于 b 4 - a 大于等于 b 5 - a 大于 b 6 - a 小于等于 b 7 - b 大于等于 a
The above are the comparison operators in python and some related examples. I hope this article can help you reading.
