遍历应该是列表python的函数参数

Question

I try to write a long program in python the first part is:

def frequence(entranche):
podium = []
for item in entranche:
    scat = len(entranche)
    for indice in range (len(entranche)):

        if entranche[indice] == item:
            scat -= 1
        frequence = len(entranche) - scat
        podium = podium.append(frequence)
    plus_haute_frequence = max (podium)   
    return(plus_haute_frequence)

print(frequence(("Je suis né dans le béton Coincé entre deux maisons Sans abri sans domicile" ).split()))

How would the program treat "entranche" as list?

Answer 1

您没有调用split方法。

entranche = poeme.split()

Answer 2

entranche = poeme.split is a function, not a list. You forgot the parenthesis, which do the actual call to the function entranche = poeme.split() and returns a list.

Answer 3

If entranche would be a list, you wouldn't see that error. So, check what entranche really is. Check its type() , or just print it.

You'll find your error here:

entranche = poeme.split 

That should be:

entranche = poeme.split()

Answer 4

there is noway to precise my question Folowing xph I try this

def frequence(entranche):
    podium = []
    print("premier podium", type(podium))
    for item in entranche:
        print ("deuxieme podium", type(podium))
        scat = len(entranche)
        for indice in range (len(entranche)):            
            if entranche[indice] == item:
                scat -= 1
            frequence = len(entranche) - scat

        podium = podium.append(frequence)
        print("troisieme podium", type(podium))
        plus_haute_frequence = max(podium)   
    return(plus_haute_frequence)
print(frequence("Je suis né dans le béton Coincé entre deux maisons".split()))

and I get a big surprise!

premier podium <class 'list'>
deuxieme podium <class 'list'>
troisieme podium <class 'NoneType'>

What is iT??
