FAQs on Python Programming Tutorial - 15 - More Methods
| 1. What are some commonly used methods in Python programming? |  |
Ans. Some commonly used methods in Python programming include the `append()` method for adding elements to a list, the `split()` method for splitting a string into a list, the `upper()` method for converting a string to uppercase, the `replace()` method for replacing a specific substring in a string, and the `sort()` method for sorting elements in a list.
| 2. How does the append() method work in Python? | |
Ans. The `append()` method in Python is used to add an element to the end of a list. It takes a single argument, which is the element to be added, and modifies the list by adding the element at the end. For example, if we have a list `my_list = [1, 2, 3]`, and we use the `append(4)` method, the list will become `[1, 2, 3, 4]`.
| 3. What does the split() method do in Python? | |
Ans. The `split()` method in Python is used to split a string into a list of substrings based on a specified delimiter. By default, the delimiter is a whitespace. For example, if we have a string `my_string = "Hello World"`, and we use the `split()` method, it will return a list `['Hello', 'World']`. We can also specify a different delimiter by passing it as an argument to the `split()` method, such as `my_string.split(',')` to split the string at commas.
| 4. How can I convert a string to uppercase in Python? | |
Ans. To convert a string to uppercase in Python, we can use the `upper()` method. It is called on a string and returns a new string with all characters converted to uppercase. For example, if we have a string `my_string = "hello world"`, and we use the `upper()` method, it will return `"HELLO WORLD"`.
| 5. How does the sort() method work in Python? | |
Ans. The `sort()` method in Python is used to sort the elements of a list in ascending order. It modifies the original list and does not return a new list. The `sort()` method works by comparing the elements of the list and rearranging them in the correct order. For example, if we have a list `my_list = [3, 1, 2]`, and we use the `sort()` method, the list will become `[1, 2, 3]`. We can also use the `sort(reverse=True)` to sort the list in descending order.

what's up guys welcome to your 15th
place on tutorial and then less story I
talked to you guys about methods and
objects and stuff in this story I want
to cover some methods that I didn't go
over there are gonna be useful later on
the first one is called index and what
the index method does is pretty much
search for the first occurrence of a
value and say um where in the list it is
so let's go ahead and make a quick
saying you can name your list say and
let's put a now brown cow and go ahead
and put your little quotes around every
word make sure I spelled everything
right brown cork what the WTF tree get
the cow now go ahead and press enter you
notice we have say make sure list is
created so let me show you guys what
index for those first plus a index again
you have your object and then you have
your method and the parameter index
takes you have to type in any element
that you want to search for in your list
so let's go ahead and search for Brown
so and what its gonna do is once we have
our object our method and our parameter
that long search for brown air returns
to and remember this is 0 1 2 so that's
how you can search for words or numbers
in given list another thing that you can
do is insert or any elements into a list
or sequence and you can do this by using
of course the insert method so have say
insert and then you have two parameters
first where you want to insert it and
second what you want to insert so say
you want to insert Hoss into position
two
this is what you would do and now do
that press ENTER and it says hey now
Hoff's brown cow of course is 0-1 you're
new to is Hoss and it kind of just push
everything over a little bit and besides
that when you have insert of course you
have to have a way to remove elements
from a list too so that method is pop so
puts a dot pop by donna me period
in the parameters you have for this is
what position in the list you want to
remove it so let's say we want to remove
let's remove now so this is 0-1 so pop 1
again object element parameters press
ENTER say and of course hey Hoss brown
cow and another thing that pop does is
unlike delete or anything like that
it actually returns the value to you
that you delete it from the list or
popped out of it so that's a little
different way where it differs from
another or all other types of common
deletions so unless you want to use this
value like in a program or something you
would use pop if not you would use
another deletion method um the second is
the last one I want to talk to you guys
about is remove in what this does is
remove the first occurrence of any word
and of course that would be your
parameter so have your object say well
this we want to remove and get out of
your list what do we want to remove um
let's remove Brown one um so let's go
ahead and do that and once we do that
you should have hey pause cow and again
this is a little different because
instead of returning a value like pop
and this is you would return a value if
you want to use this value in a program
it just deletes it from the list and
doesn't return it at all so that's one
way to remove differs from pop and the
last one I'm going to talk to you guys
about is reverse so say I'm not even
going to tell you guys what this one
does pretty self-explanatory again our
old list hey Hoss cow our new list cow
Hoss hey can't figure out what went on
there with the keyword reverse well
that's a shame
so that is how you use all those methods
um in the next tutorial I'm gonna be
showing you guys some awesome way how to
sort so I would pay attention if I was
you and I would also subscribe if I was
you so thank you guys for watching and I
look forward to teaching you next time
