Python Notes

String / String Literals  [' ' or " " but no mix, have to be consistent]
=============================================================
    - strings in Python have data type 'str'
    - str is Unicode (Python 3  source endcoding UTF-8)
    - date type of strings (in Python)  
    - sequence of Unicode code points (like characther but exactly not that)
    - immutable (cant change/modify it's content)
    - string constructor: str() [used to represent string from other type]
Strings with Newlines:
========================
[1] multiline strings
    - spread the literal across multiple lines
    - use: """   """ or '''  ''' [covered by 3 single / double quotes] =>  '... \n ...'
    [Universal Newlines]
    - Python translates \n - to appropriate newline sequence for your platform (windows/mac/linux)
[2] escape sequences (embaded escapse sequences in a ling-line literal)
    - 'a \' in a string'        # 'a ' in a string'
    - 'a \\ in a string'        # 'a \ in a string'
 
 
 path = r'C:\a.txt' # 'C:\\a.txt'   [raw string ]
 str(123)           # '123'         [constructor]
 s = 'few steps'
 s[2]               # 'e'           [sequence types]
 type(s[2])         # 
 help(str)                          [string has lots of methods]
 s.capitalize()     # Few Steps

Merge/join two or more video files using Python

By
Using Pyhton, we can easily add two or more videos files easily. We just need to use the moviepy package. Once we import that package, we can ean use the methods or functions to add movie files. Here, in this tutorial, we joined/merged two video files. But it is not limited to add only two video files. We can add multiple video files using the same program with the change of no of files expressions. Just import all the movie files and then join using the same concept. from moviepy.editor import * # load clips clip_01 = VideoFileClip('nature.mp4') clip_02 = VideoFileClip('rain.mp4') # join + write result_clip = concatenate_videoclips([clip_01, clip_02]) result_clip.write_videofile('combined.mp4') Here, in this program we imported the moviepy package. Later, we loaded two video files. If you want to add multiple video files, just import all of them. Finally, we concatenate by using the method concatenate_videoclips() and we saved it in the directory locat...
