False

A call to a function in Python may return multiple values of multiple types by returning a "tuple".

True

False

Explanation / Answer

TRUE

Python data-types are generally associated with the values of identifiers whereas Java data-types are associated with the identifiers themselves

In Python there is no need to declare variable datatype before using it. In Python, we just simply assign the value to a variable,python internally does the data type assignment according to the type of data we provide

But in case of we have to provide the data type ov variable while declaring it.

FALSE ,The value of xyz will remain the same because return statement will put the value from where it is called and moreover xyz in function is a local variable.

True ,after a list is created the values within the list may be freely altered ,here are some functions to alter the list

insert(): adds a new entry at the index specified in the list

append():It adds a new entry to the last of the list.

clear(): removes all values from the list.

.remove(): Removes entry from the specified position in the list.

TRUE

call to a function in Python may return multiple values of multiple types by returning a "tuple".

I will show a example.
