built-in functions of python

# print (abs(-1)) #Absolute value 
# print (all([1,2,'1']))# Take each value in the sequence and do a Boolean operation, as long as one is false, return false 
# print (all('hello'))#return true 
# print (all(""))#if the iterable is empty, also return true 
# print (any(['0','2']))# As long as one is true, it is true 
# print bin(2) # Decimal to binary 
# print bool('') # Compute false 0 for boolean values, and boolean values ​​for null and None are both false 
# print (bytes( 'Hello')) 
#name = 'Hello' 
# name='Hello' 
#The following are all in Python3 
# print(bytes(name,encoding='utf-8')) 
# print(bytes(name, encoding='utf-8').decode('utf-8')) 
# print(bytes(name,encoding='gbk')) 
# print(bytes(name,encoding='gbk').decode('gbk ')) 
# print(bytes(name,encoding='ascii'))#ascii cannot encode Chinese# 

print chr(10)#corresponding to ascii code table 
#print dir(dict)#print what methods are under an object
#print (divmod(10,3))# Take the quotient and take the remainder, often used for paging functions 
seasons = [ 'Spring', 'Summer', 'Fall', 'Winter'] 
print list( enumerate(seasons)) # The enumerate() function is used to combine a traversable data object (such as a list, tuple or string) into a sequence of indices, listing both the data and the data subscripts
