Tuples can be thought of as read-only lists. For example − #!/usr/bin/python3 tuple = ( 'abcd', 786 , 2.23, 'john', 70.2 ) tinytuple = (123, 'john') print (tuple) # Prints complete tuple print (tuple[0]) # Prints first element of the tuple print (tuple[1:3]) # ...

(discrete/continuous) and then calls`layout_changed` - `layout_changed` constructs all the elements for the scene (as lists of QGraphicsItemGroup) and calls `display_changed`. It is called when the attribute or grouping is changed (by attr_changed) and on resize event. - `display_changed`...
tuples– similar to lists, tuples in Python are used to store a set of elements under a single variable name. However, unlike lists, they cannot be changed once created. You can thought of tuples as read-only lists. They are used to represent fixed collections of elements, like days in...

A variable is a reserved memory location that can store some values. In other words, a variable in a Python program gives data to the computer for processing the operations. Every value in Python has a data type. There are numbers, lists, tuples, and more in Python. ...
With all these 3 functions, we say that PHP supports variable-length argument lists with some basic rules: The function call can provide more arguments than the number of argument variables defined in the function statement. You can pass arguments to a function that has no argument variable ...
Strings, lists, and tuples are examples of sequence-type(compound data types) in Python, so-called because they behavelike a sequence – an ordered collection of similar or different data types. Python has the following standard sequencedata types: ...
This lesson will explain what is variable scope in Python. Two types of variables, local and global, will be explained with the help of examples...
