def freq(str): 
  
    # break the string into list of words  
    str = str.split()          
    str2 = [] 
  
    # loop till string values present in list str 
    for i in str:              
  
        # checking for the duplicacy 
        if i not in str2: 
  
            # insert value in str2 
            str2.append(i)  
    
    # sorting list
    s = sorted(str2)
    for i in range(0, len(s)): 
  
        # count the frequency of each word(present  
        # in str2) in str and print 
        print( s[i], ':', str.count(s[i]))     
  
def main(): 
    str = input("Enter the sentence: ")
    freq(str)
