Remember also: strings 16 #are immutable, so operations like my-string . lower() don't 17#change the value of my string like list methods: to save 18 #those results, you'd write my-string-my-string. lower() 19,#Your dictionary should not have any duplicate keys (in fact, 26#Python ?0n't allow a dictionary to have duplicate keys) 21 23#Write your function here! 24 Below are sone lines of code that will test your function 26#You can change the value of the variable(s) to test your 27#function with different inputs 28 | # 29#If your function works correctly, this will originally #print : 32 | # 3#The order of the keys may differ, but that's okay! 34 print (word_lengths ("I ate a bowl of cereal out of a dog bowl today.))
