This Python tutorial will teach you to useIf Not in Python, with multiple examples and realistic scenarios. TheNot operator is a logical operator in Pythonthat can be used in theIf condition. It returns theopposite result of the condition. This means thatif the condition is Truebut you are ...
An understanding of operator precedence is fundamental when it comes to using Python operators. The concept comes from arithmetic and is known as “point before dash calculation”. Just to remind you, the expression 3 * 8 + 2 is interpreted as (3 * 8) + 2, not 3 * (8 + 2). As ...
The 'Not Equal' Operator in Python The 'Not Equal' operator (!=) is a relational operator that compares two values for inequality. Below is an example of the syntax: value1 != value2 Powered By If value1 is not equal to value2, the expression returns True; otherwise, it returns Fal...
The most important use of the**operator comes while sending multiple arguments to a function. One must have seen the use of thekwargskeyword in function definitions. We use this in a function definition, which is considered a standard notation when we do not know the total parameters of the...
In the above code, you can see the function’s first use of the modulo operator: Python current_key = key[i % len(key)] Here, the current_key value is determined based on an index returned from i % len(key). This index is used to select a letter from the key string, such ...
The "NOT IN" the filter is used to check whether a particular data is available in the DataFrame or not. The "NOT IN" the condition in pandas is checked by using the DataFrame.isin() operator.How to Use 'NOT IN' Filter?To use the "NOT IN" filter in Pandas, you can use the ...
As soon as we set a variable equal to a value, weinitializeor create that variable. Once we have done that, we are set to use the variable instead of the value. In Python, variables do not need explicit declaration prior to use like some programming languages; you can start using the ...

Using a Range with Python For Loops The most basic for loop use in Python is to iterate over a range, essentially creating a loop that will only iterate for a set number of times. While “range” is not strictly part of the syntax for a for loop, it is really a built-in Python fu...
Python arrays can be combined, or concatenated, using the + operator. There are other ways to go about combining arrays — using a loop, for instance. But the + operator provides the most convenient method if your goal is simply to join two or more arrays. In the example below, the exa...
