Python Tuples

Tuples in Python

Tuples are immutable versions of lists.
A tuple is a collection of values, and declare it using parentheses, ( and ).

immute_set=('one', 2, 'three', 'banana')

>>> tup_python = (23, 'abc', 4.56, (2,3), 'def')
a, b, c = tuple_with_3_values
>>> mytuple=((1,2),(3,(4,5),(6,(7,(8,9)))))
(count, i, list) = (0, 1, [])
(m, n) = (n, m) # swapping two values

tuple2[i]         #ith element, from left

                      Positive index: count from the left, starting with 0

                      Negative index: count from right, starting with –1

tuple1[16]
tuple_py[-4]

tuple2[m:n]    #n elements from mth position

                     Return a copy of the container with a subset of the original members.
                     Start copying at the first index, and stop copying before second. m ≤ i < n.

tup_python[m:n:increment]

tup[12:16]
tup[2:8:2]
>>> mytuple[1][2][1][1][0]
>>> t[::-1]

len(py_tup)
tup_python[len(tup)::-1]                 # to reverse tuple

tuple9.index('b')

>>> (1,3,2).index(3)

tuple9.count('b')

print(sorted(pyTuple))

min(tup)

>>> max((1,3,-1))

python_tu = tuple(li)

tuple2 = tuple1

type(python_tu)

>>> t[:]

>>> myTuple * 3

>>> [x*y for x in vec1 for y in vec2]

>>> [3*x for x in vec if x > 3]
