Formula and generators

Generative

F DEF (n-): 
    return. 3 ** n- 
A = [F (X) for X in Range (10)] This formula is a simple 
print (a) # [0, 1, 8, 27, 64, 125 , 216, 343, 512, 729] 
Print (type (A)) # <class 'List'> 
B = ( 'ssss', 88) 
C, T B = 
Print (C, T) 88 #ssss 
generator

s = (x for x in range (5)) # differs from s = [x for x in range ()] which is formula 
print (s) # <generator object <genexpr> at 0x000000000222A848> generating addresses 

print (next (s)) # is equivalent to print (s .__ next __ () ) this method is usable python2 
print (next (s)) # can be individually removed so that the contents inside the generator 
Print (Next (S)) 
Print (Next (S)) 
Print (Next (S)) 
for I in S: # generator is a iterable Iterable this is another way to take a value generator 
    print (i) 
another way of key generator yield word 
DEF foo (): 
    Print ( 'ssss') 
    the yield. 1 
    Print ( 'TTT') 
    the yield 2 
# Print (foo ()) # <Object Generator AT 0x00000000021FA848 foo> 
G = foo () 

# Next (G) #ssss 
# the Next (G) # TTT 
for i in G:#for loop iteration behind the object is added (iter can call methods are iterable as tuples, lists, dictionaries) 
    Print (I). 1 TTT 2 #ssss
