why are u using jupyter instead of IDLE python 3
Jupyter vs IDLE python 3
Jupyter notebook allows to write codes in snippets or blocks which allows better handling of the code and makes it more readable and understandable .Also by writing codes in snippets error detection and handling becomes easier.
Also Jupyter notebook provide additional features like inline graph and auto completion of function or variable name using tab which save time .It also allow markdowns to be inserted in the code which also helps in readability and documentation of the code.
Thats why we prefer using Jupyter as it makes understanding and organizing our codes easier.
Not only that most of the mnc using python uses notebook similar to jupyter
