Mar 9, 2009 · The PEP 484 -- Type Hints says that the types of elements of a tuple can be individually typed; so that you can say Tuple[str, int, float]; but a list, with List typing class can take only one type parameter: List[str], which hints that the difference of the 2 really is that the former is heterogeneous, whereas the latter intrinsically homogeneous.

Sep 9, 2014 · A tuple is a good way to pack multiple values into that cookie without having to define a separate class to contain them. I try to be judicious about this particular use, though. If the cookies are used liberally throughout the code, it's better to create a class because it helps document their use.

Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i.e. the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on. See Common Sequence Operations:

Apr 5, 2012 · Note: This is asking for the reverse of the usual tuple-to-array conversion. I have to pass an argument to a (wrapped c++) function as a nested tuple. For example, the following works X = MyFunc...

A tuple is used to define a slice of data from a cube; it is composed of an ordered collection of one member from one or more dimensions. A tuple is used to identify specific sections of multidimensional data from a cube; a tuple composed of one member from each dimension in a cube completely describes a cell value.

Apr 25, 2022 · not using ellipsis means a tuple with specific number of elements, e.g.: y: tuple[str] = ("hi", "world") # Type Warning: Expected type 'Tuple[str]', got 'Tuple[str, str]' instead This goes in contrast to notation of other collections, e.g. list[str] means list of …

Jun 4, 2010 · It's a specific subclass of a tuple that is programmatically created to your specification, with named fields and a fixed length. This, for example, creates a subclass of tuple, and aside from being of fixed length (in this case, three), it can be used everywhere a tuple is used without breaking. This is known as Liskov substitutability.

Jun 25, 2013 · This is what is called a tuple, obj is associated with 4 values, the values of s1,s2,s3,s4. So, use index as you use in a list to get the value you want, in order. obj=list_benefits() print obj[0] + " is a benefit of functions!" print obj[1] + " is a benefit of functions!" print obj[2] + " is a benefit of functions!"

>>> tuple = 45, 34 # You used `tuple` as a variable here >>> tuple (45, 34) >>> l = [4, 5, 6] >>> tuple(l) # Will try to invoke the variable `tuple` rather than tuple type. Traceback (most recent call last): File "<pyshell#10>", line 1, in <module> tuple(l) TypeError: 'tuple' object is not callable >>> >>> del tuple # You can delete the object ...

*t means "take all additional positional arguments to this function and pack them into this parameter as a tuple." def foo(*t): print(t) >>> foo(1, 2) (1, 2) **d means "take all additional named arguments to this function and insert them into this parameter as dictionary entries."
