Python PIP

 

Python PIP

What is PIP?

PIP is a package manager for Python packages, or modules if you like.

Note: If you have Python version 3.4 or later, PIP is included by default.

What is a Package?

A package contains all the files you need for a module.

Modules are Python code libraries you can include in your project.

Check if PIP is Installed

Navigate your command line to the location of Python's script directory, and type the following:

Example

Check PIP version:

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip --version

Install PIP

If you do not have PIP installed, you can download and install it from this page: https://pypi.org/project/pip/

Download a Package

Downloading a package is very easy.

Open the command line interface and tell PIP to download the package you want.

Navigate your command line to the location of Python's script directory, and type the following:

Example

Download a package named "camelcase":

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip install camelcase

Now you have downloaded and installed your first package!

Using a Package

Once the package is installed, it is ready to use.

Import the "camelcase" package into your project.

Example

Import and use "camelcase":

import camelcase

c = camelcase.CamelCase()

txt = "hello world"

print(c.hump(txt))

Find Packages

Find more packages at https://pypi.org/.

Remove a Package

Use the uninstall command to remove a package:

Example

Uninstall the package named "camelcase":

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip uninstall camelcase

The PIP Package Manager will ask you to confirm that you want to remove the camelcase package:

Uninstalling camelcase-02.1:
  Would remove:
    c:\users\Your Name\appdata\local\programs\python\python36-32\lib\site-packages\camecase-0.2-py3.6.egg-info
    c:\users\Your Name\appdata\local\programs\python\python36-32\lib\site-packages\camecase\*
Proceed (y/n)?

Press y and the package will be removed.

List Packages

Use the list command to list all the packages installed on your system:

Example

List installed packages:

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip list

Result:

Package         Version
-----------------------
camelcase       0.2
mysql-connector 2.1.6
pip             18.1
pymongo         3.6.1
setuptools      39.0.1

Python Tuples

  Python  Tuples mytuple = ( "apple" ,  "banana" ,  "cherry" ) Tuple Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and  unchangeable . Tuples are written with round brackets. Example Create a Tuple: thistuple = ( "apple" ,  "banana" ,  "cherry" ) print (thistuple) Tuple Items Tuple items are ordered, unchangeable, and allow duplicate values. Tuple items are indexed, the first item has index  [0] , the second item has index  [1]  etc. Ordered When we say that tuples are ordered, it means that the items have a defined order, and that order will not change. Unchangeable Tuples are unchangeable, meaning that we cannot change, add or remove items after the tuple has been created. Allow Duplicates Since tuples...

Python Arrays

  Python  Arrays Note:  Python does not have built-in support for Arrays, but  Python Lists  can be used instead. Arrays Note:  This page shows you how to use LISTS as ARRAYS, however, to work with arrays in Python you will have to import a library, like the  NumPy library . Arrays are used to store multiple values in one single variable: Example Create an array containing car names: cars = [ "Ford" ,  "Volvo" ,  "BMW" ] What is an Array? An array is a special variable, which can hold more than one value at a time. If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this: car1 =  "Ford" car2 =  "Volvo" car3 =  "BMW" However, what if you want to loop through the cars and find a specific one? And what if you had not 3 cars, but 300? The solution is an array! An array can hold many values under a single name, and you can access the values by referring to an index nu...

Python Strings

  Python  Strings  Strings Strings in python are surrounded by either single quotation marks, or double quotation marks. 'hello'  is the same as  "hello" . You can display a string literal with the  print()  function: Example print ( "Hello" ) print ( 'Hello' ) Assign String to a Variable Assigning a string to a variable is done with the variable name followed by an equal sign and the string: Example a =  "Hello" print (a) Multiline Strings You can assign a multiline string to a variable by using three quotes: Example You can use three double quotes: a =  "" "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua." "" print (a) Or three single quotes: Example a =  '' 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.' '' print (a) Note:  in the res...
