3. map # treated string list, the list of all become sb, for example alex_sb 
name = [ 'Alex', 'wupeiqi', 'yuanhao', 'Nezha'] 
# DEF FUNC (Item): 
# return Item + '_ SB'

# for I in RET: 
# Print (I) 
# Print (List (RET)) 

# RET = Map (the lambda Item: Item + '_ SB' , name)

# 4. a digital filter function processing list, the list will filter out all of the even numbered 
# NUM = [1,3,5,6,7,8] 
# DEF FUNC (X ): 
#% 2 == 0 X IF: 
# return True 
# RET = filter (FUNC, NUM) #RET iterators 
# Print (List (RET)) 
# 
# RET = filter (the lambda X: X% 2 == 0, NUM) 
# RET = filter (the lambda X: IF True X False the else% 2 == 0, NUM) 
# Print (List (RET)) 

# 5. the free to write more than one line in the file 20

# The page_num = int (INPUT ( "Please enter the page: ')) 
# pages, divmod MOD = (len (L),. 5) # find how many pages there are no remaining rows 
# if mod: # if the number of remaining rows, the number of pages plus a 
# pages + = 1 # a total number of page 
# if page_num> pages or page_num < = 0: # of pages input by the user or less than the total number 0 
# Print ( 'mistyped') 
# == pages elif the page_num and mod = 0:! # If the page is the last page of the user input, and before there remaining rows 
# for I in Range (MOD): 
# Print (L [(. 1-the page_num). 5 * + I] .strip ()) # output only on the remaining lines of the page 
# the else:
