I. Cheat Sheets
Create your own cheat sheets. They will tell you what you should learn by heart. You can create beautiful cheat sheets using Keynote, PowerPoint or something like that. Let me show you my cheat sheets though they are not completed yet.
II. How to use ( ), [ ], and { }
Certainly, parentheses, square brackets, and braces are very confusing for beginners but it makes you feel at ease to know the following general usage of them when you understand and memorize snippets.
1.Square brackets [ ]
- Creating lists
- Requesting items
2.Curly braces { }
- Creating dictionaries
- Creating sets
- f-strings
3.Parentheses ( )
- Callables (functions and classes)
- Creating tuples
- Cheating Python’s indentation rules
In the Cheat sheets I have shown some scripts similar to R scripts with pipes using ( ):
df0 = pd.read_csv("https://pastebin.com/raw/cSZ8pYWh")
(df0. # about df0
filter(['english', 'japanese']). # select columns
mean(). # get the means
to_frame(name = 'average') #
)
