The following example converts a time string into adatetime.time()object, and prints the class type and value of the resulting object: fromdatetimeimportdatetime time_str='13::55::26'time_object=datetime.strptime(time_str,'%H::%M::%S').time()print(type(time_object))print(time_object) C...
A great convenience when working with Python, especially in the interactive shell, is its powerful introspection ability. Introspection is the ability of an object to know about its own attributes at runtime. For instance, a function knows its own name and documentation:...
The type() function returns the data type of a given object. Example 1: Python 1 2 3 4 # Checking the data type of a variable x = 100 print(type(x)) Output: Explanation: Here, type() returns the data type of the variable. Example 2: Python 1 2 3 4 # Checking the data ty...
