python generation expression

Learn a code amount can save a lot, but also facilitate the use of 
the following are a few examples: 

# list creating the expression 
A = [I for I in Range (. 5)% 2 == 0 I IF] 
Print (A) 
# dictionary generation expression 
I = {B: I% 2 == 0 for I in Range (10)} 
Print (B) 
# tuples for the generation of an expression, which is not called tuples generated expression, called generator expression 
c = (c Range in C for (10)) 
Print (C) is a C # generator 
Print (SUM (C)) # expressions can be generated as a function of the parameter 
print (sum (range (5) ))
