Pythonnot equal operator returnsTrueif two variables are ofsame type and have different values, if the values are same then it returnsFalse. 如果两个变量具有相同的类型并且具有不同的值,则Python不等于运算符将返回True;如果值相同,则它将返
Here, str1 and str2 are not the same string, resulting in True. Be cautious, however. Capitalization counts with this method, meaning “Hello” will be considered to not be equal to “hello.” Key takeaway: The != operator is the standard method for checking inequality. Combining logic wi...
Python不等于运算符(Pythonnot equal operators) Operator Description ! = 不是Equal运算符,可在Python2和Python3中使用。 <> 在Python2中不等于运算符,在Python3中已弃用。 我们来看一些Python2.7中不等于运算符的示例。 如果您使用的是Python3.6或更高版本,我们也可以将Python不等于运算符与f字符串一起使用。

Watch it together with the written tutorial to deepen your understanding: Using the Python not Operator Python’s not operator allows you to invert the truth value of Boolean expressions and objects. You can use this operator in Boolean contexts, such as if statements and while loops. It also...
Enum string comparison To compare a string with an enum, extend from thestrclass when declaring your enumeration class, e.g.class Color(str, Enum):. You will then be able to compare a string to an enum member using the equality operator==. ...
| operator. | | assertEquals = assertEqual(self, first, second, msg=None) | | assertFalse(self, expr, msg=None) | Check that the expression is false. | | assertGreater(self, a, b, msg=None) | Just like self.assertTrue(a > b), but with a nicer default message. ...
This is, of course, silly behavior for an object that otherwise behaves as a string, but it does illustrate what happens when you compare two objects using==. The!=operator gives the inverse response of this unless a specific__ne__()class method is implemented. ...
