General Information:
Whitespace matters ! Indent where needed Import modules " import modulename"
# This is a command
print (" Hello World by #VendanNotes ! ")
Note..! Prints to Screen
Conditional Statement:
if isSunny :
print ( ' It's sunny !' )
elif go <= temp < 100 and bath >80:
elif not ((job == 'qa') or(usr ==' adm '):
print (' Match if not qa or adm')
else :
print('No match job is't + job)
Strings :
title = 'US and them '
#most list operations works on strings Works on Strings
title[0] #output: ' U'
len (title) #11
title.split (' ') #['US' , ' and ' , ' them ' ]
':' join ([ 'A','B','C']) # ' A ' , ' B ' , ' C '
nine = str (g) # Convert int into string
title.replace('them' , 'us' ) # US and US.
Dictionaries:
votes = { 'red':3 , 'blue' : 5}
votes.keys () #output: ['blue' , 'red']
votes [ ' gold ' ] = 4 #add a key / val
del votes [' gold '] #deletes key
votes ['blue'] = 6 #change value
len (votes) #2
votes.value() # [ 6,3 ]
'green' in votes #false
votes.has_key('red') #true
Numbers:
total = 3 * 3 #output:9
total = 5 +2 *3 #output:11
cost = 1.50 + 3.75 #output:5.25
total = int (" g ") + 1 #output:10
Tuples :
Like lists , except they cannot be changed
tuple 1 = (1,2,3, " a " , " z ") #creates tuple
tuple1 [3] # ' a '
lists:
Scores = [' A ' , 'C' , 90 , 75 , 'c' ]
Scores [ a] #Output : ' A '
Scores [1:3] # ' C ' , 90
Scores.count ('c') # 2
Scores.append (100) #Adds 100 70 list
Scores.pop() #removes third item
