Python #list #tuple #set #dictionary

1. List :
It is used to store multiple items in single variable.
In list,

Items will be in order.
We can change items.
It allows duplicate of items .

mylist = ['dog','cat','monkey','cat'] mylist[0]='cow' print(mylist)
Output:

['cow','cat','monkey','cat']

2. Tuple :
It is used to store multiple items in single variable.
In tuple,

Items will be in order.
We can not change items.
It allows duplicate of items

mytuple = ('dog','cat','monkey','cat') mytuple[0]='cow' print(mytuple)

Output:

TypeError: 'tuple' object does not support item assignment

3. Set :
It is used to store multiple items in single variable.
In set,

Items will not be in order.
We can not change items.
It do not allows duplicate of items -(in below example cat will be showed only once when you print myset)-.

myset = ('dog','cat','monkey','cat') myset[0]='cow' print(myset)

Output:

TypeError: 'set' object does not support item assignment

4. Dictionary :
It is used to store multiple items in single variable.
In dictionary,

Items will be in order.
We can change items.
It do not allows duplicate of items .

mydictionary = {'dog':'moo','cat':'meow','cat': 'meow''lion':'roar'} mydictionary['dog']="bark" print(mydictionary)

Output:

{'dog': 'bark', 'cat': 'meow', 'lion': 'roar', 'cow': 'moo'}

*In day 04 I have learned *

To create remote.
git remote add remote-name https://(from server)
To see created/available remote.
git remote
To see details about remote.
git remote -v
To push the code/file's to server
git push **remote-name** branch-name
To clone existing file from server's:
git clone https:/(from server file)
To push cloned update file to server:
git push origin branch-name

origin is default remote of cloned file.

Have a great day 😊.
