查找用户在Python中输入的单词长度

Question

I am new in learning Python. And I thought of writing a code.

I want the user to input some words, and I want the program to give the length of the words as output.

words = [raw_input("Enter a name: ")]

def len_name(words):
    for x in words:
        print(x, len(x))

len_name(words)

Now, when the user gives a single word as input, say aeroplane, the program gives the following output and that's correct.

Enter a name: aeroplane
('aeroplane', 9)

But if user give two words as output, it give the following:

Enter a name: aeroplane, fish
('aeroplane, fish', 15)

I was looking for the code to give different words and their length.

What did I mess up?

Answer 1

words = [raw_input("Enter a name: ")] takes the input and puts it in a list as a single element: ['aeroplane, fish'] . In order to obtain ['aeroplane', 'fish'] , you need to split the input with an appropriate delimiter:

words = raw_input("Enter a name: ").split(', ')
# or a little more robustly wrt white space:
words = [w.strip() for w in raw_input("Enter a name: ").split(',')]

Answer 2

You are current reading in a line, so it doesn't care about what is there in terms of spaces, or common separated words etc.

So you need to split the read in line into words using split

Answer 3

A simple fix to your current code would be to not create a list for the multiple words since they are all one entry, and then .split(', ') that entry when its passed to len_name() and then do as you were with for i in x . Also functions should return a value not just print. A revised version would be:

def len_name(x):
    lista = []
    for i in x.split(', '):
        lista.append((i, len(i)))
    return lista

words = input('Enter a name: ')
word_len = len_name(words)
for i in word_len:
    print(*i)

 Enter a name: vash, the, stampede vash 4 the 3 stampede 8 

Or using list comprehension and a loop to print

word_len = [(i, len(i)) for i in input('Enter a name: ').split(', ')]
for i in word_len:
    print(i[0], i[1])
