#Why are strings immutable?
#   cannot change content of string
#   functions return a new string that has been modified from original


#list is mutable = object can change
#list[0] = 5 #has just changed the first element of list to 5

###################
#length of strings counts literal letters, spaces within single quotes, punctuations
#strip() = gets rid of whitespaces in beginning and end
#replace() = gets rid of all occurences of spaces in the string

###################

x = [ 3, 1, '4', True ]
x.append( '20' ) #adds '20' to end of list x
print( x )

x = x.append( 11 )
print( x )
#when appending to a list, do not assign list = list.append(...)!

###################

#when sorting strings, if string contains letters, sort by alphabetical order
#when strings contain #'s, lexicographical order
#look at characters one by one
#so, 'A141' < 'A3' because 1 < 3
#so, max( v ) = 'A59'

###################

#Python stores decimal in limited bits (64) --> most digits ~~15-16 digits

###################

print() #print empty line in console

reply = input( 'Enter four strings: ' )

strings = reply.split() #list of inputs

sorted_strings = sorted( strings ) #sorted list of strings

#no accumulator because you don't have to build anything here

for s in sorted_strings:
    print( s ) #just printing vertically each element in the sorted_strings list

#make sure your output matches up exactly with sample run!!!

####################

#to "remove" a character from a string
#   str.replace( old_value, '' ) #removes value you want to replace and
#       replace with empty string aka nothing aka '' aka no space
