built-in function

Anonymous function: lambda n: print(n) 
all objects are non-zero or True, and empty is False #If
 all objects in all() are true, return True, otherwise False 
a = all([ " aaa " ,12 ,0 ])
 print (a)

#If any of the objects in any() is true, return True, otherwise 
a = any([ " aaa " ,12 ,0])
 print (a)

#Decimal to binary 
a=bin(255 )
 print (a)

#Print out the Ask code of a certain word 
a=bytearray( " abcdef " ,encoding= " utf-8 " )
 print (a)

#Absolute value 
a=abs(-100016 )
 print (a)

# #Accumulated instances of built-in functions 
import functools
res = functools.reduce(lambda x,y:x+y,range(100))
print(res)

# # Turn a set into an immutable set 
a = frozenset([12,3,5,8,5,6,5,4])

# ##Precise floating point number 
round(1.3334,2 )
 # #2, this is how many decimal places to keep

# # Sort a dictionary into a list 
a= {6:2,8 :0}
 print (sorted(a.items))
