mastery24 Creation and use of tuples in Python

#TC1014 #Mastery24

In this mastery I will talk about tuples.A tuple is a sequence of immutable Python objects, is like lists, but they have on especially diference, that ones yu create a tuple you can not modify but in lits you can. Also the sintax of tuples are parentheses and lists use square brackets.for example:

tuple1=(“efrain”,”duarte”,”lopez”,20)

you can write strings,numbers is just like lists.

be careful when you just write one thing inside a tuple you have to write it like this:

tuple2=(“ice”,) ——> such is just one thing you have to add a comma to the end

To acces values in tuples  you have to use square brackets.for example:

tuple1=(“efrain”,”duarte”,”lopez”,20)

print tuple[0]——–>the result will be “efrain”

print tuple[0:2]—–>the result will be [“efrain”,”duarte”,”lopez”]

this is counting beging form 0.

You cant modify a tuple but you can create a new tuple with other tuples like this:

tuple3=tuple1+tuple2

tuple3 will be>>>(efrain”,”duarte”,”lopez”,20,”ice”)

Also the tuples respond to the + and * operators much like strings, and this operations will create a new tuple not just strings .For example the basic tuples operations:

tuple4=(1,2,3,4)

print  lent(tuple4)——>resutl= 4

also we can use Concatenation,Repetition,Iteration.

an important point is that we can modify a list inside a tuple, but the tuple we can n ever touch it.
