“There is no failure, only trying.”

Ok Let’s try to make a list of symbols, see how well I understand and recall their functions. It’s going to be tedious but the end goal is to create a reference table with my own words, which can help me review in the long term.

#	Hash, Mesh or octothorpe	To comment out a piece of code, or make a note for future reference
print		Show a statement or string on the screen
‘’	Single quote	For short string
“”	Double quote	For longer string
“”” “””	Triple quote	For paragraph
variable		A value container, we store data in them
(f”)	String format	A convenient way to write string with variable in a print functionEx: print(f”If I add {age}, {weight}, and {height} I get {total}.”)
.format()	Single Format	Format a specified value and insert them inside the string’s placeholderEx:hilarious = False (A boolean value)joke_evaluation = “Isn’t that joke so funny?! {}“print(joke_evaluation.format(hilarious))
\n	Line break escape	To put a linebreak between lines in a string
\t	Tabbing escape	To indent a string
\split	Splitting escape	To split a string
\\	Double backlash escape	To print out a backlash in a string
input()	Input method	To prompt user to input value
int()	Integer converter method	To convert a string to integer value for mathematical usages
argv	Argument Variable	To capture variable, unpack and assign values by the user to the variable names assigned to ARGV
open()	Open method	To take filename & return file object
read()	Read method	To access file object & return content
close()	Close method	To close the opened file
open(filename, ‘w’	‘w’ = write only mode	Write or overwrite content of an existing file (it will automatically truncate content first)
.truncate()	Truncate	To wipe out content in an existing file object
.write	Write	To write content in a file
exists	Exist	To check file’s availability in boolean format
len()	Length	To return the length of the string
def	keyword	To denote a method’s definition
+=	Positive increment	Add to existing variable value.  (variable +=  1 is the same as variable = variable + 1 )
return	Return statement	To send the function’s result back to the caller.
.seek	Look method	To find a specific place by byte in the file’s contentsEX.seek(0): get to the first character of the string
