Is there a way to check if the type of a variable in python is a string, like:
isinstance(x,int); for integer values?

The most efficient way to check if a string is an integer in Python is to use the str. isdigit() method, as it takes the least time to execute. The str. isdigit() method returns True if the string represents an integer, otherwise False .
Method #1 : Using isinstance(x, str) This method can be used to test whether any variable is a particular datatype. By giving the second argument as “str”, we can check if the variable we pass is a string or not.
The typeof operator is used to obtain the System. Type object for a type. It is often used as a parameter or as a variable or field. It is used to perform a compile time lookup i.e. given a symbol representing a Class name, retrieve the Type object for it.
The two common types of variables that you are likely to see are numeric and string.
In Python 2.x, you would do
isinstance(s, basestring) basestring is the abstract superclass of str and unicode. It can be used to test whether an object is an instance of str or unicode.
In Python 3.x, the correct test is
isinstance(s, str) The bytes class isn't considered a string type in Python 3.
