Code:

#Code to change all 4 character words to #### and 5 character words to @@@@@ 6 character words to !!!!!!


def fun(x):
   
     
    
    ls=x.split(" ")
    
    z=[]
    
    st=""
    
  
    
    for i in ls:
        
        if len(i)==4:
            z.append("####")
            
        elif len(i)==5:
            z.append("@@@@@@")
        
        elif len(i)==6:
            z.append("!!!!!!")
        
        else:
            z.append(i)
            
    for i in z:
        
        st=st+i+" "
    
    return st
    
    
    
    
    
    
f = open("a.txt", "r")
x=f.readline()
f.close()



z=fun(x)


text_file = open("a.txt", "w")
n = text_file.write(z)
text_file.close()

print("The text has been changed and stored in a.txt")

Output:
