pandas will attempt to infer the `dtype`from the data.Note that when `data` is a NumPy array, ``data.dtype`` is*not* used for inferring the array type. This is becauseNumPy cannot represent all the types of data that can beheld in extension arrays.Currently, pandas will infer an exte...

last string is not empty, sobool()will return True inside if condition. Hence statement inside the if condition is executed. 6. Using == Operator The==operator is used to test equality between two values. It returnsTrueif the values are equal, andFalseif they are not. You can use the...
Python’s in and not in operators allow you to quickly check if a given value is or isn’t part of a collection of values. This type of check is generally known as a membership test in Python. Therefore, these operators are known as membership operators....
