In the following example, the “OR” operator is used along with the “if-statement” to compare two conditions. Multiple conditions are applied to the given data with the help of the “OR” operator. It will return “True” if either of the conditions is satisfied: Code: Number = 45 i...
Whenever the boolean_expression evaluates to True, the statements inside the if block is executed.The not operator in python is used to negate the output of a boolean expression. In other words, if a boolean expression evaluates to True, we can use the not operator with it to make the ...
In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...

repl can be either a string or a callable; if a string, backslash escapes in it are processed. If it is a callable, it's passed the match object and must return a replacement string to be used. In [35]: url Out[36]: 'www.magedu.com' In [37]: re.sub("ma","MA",url) Out...
Python language offers some special types of operators like the identity operator and the membership operator. They are described below with examples. Identity operators In Python, is and is not are used to check if two values are located at the same memory location. It's important to note th...

This is a short-circuit operator, so it only evaluates the second argument if the first one is true. not has a lower priority than non-Boolean operators, so not a == b is interpreted as not (a == b), and a == not b is a syntax error. ...
