To whom it concerns,
When I run return, it does not work like a champ; when I run print, it prints out good. What did I do wrong? My goal is to return the value in a list. Below is the return function:
def wordcount(mylist): #define a wordcount func
for i in mylist: # create a first loop to iterate the list
for c in "-,\_.": #create a sec loop to iterate the punctuation
i=i.replace(c," ") # replace the punctuation with space
a=len(i.split()) #split the str with space and calculate the len
return (a)
mylist=["i am","i,heart,rock,music","i-dig-apples-and-berries","oh_my_goodness"]
wordcount(mylist)
It returns 2, I need [2,4,5 3]. Below is the print function, it returns 2 4 5 3. How can I fix this problem? I have been searching for quite a while. Thanks a lot!
def wordcount(mylist):
for i in mylist:
for c in "-,\_.":
i=i.replace(c," ")
a=len(i.split())
print (a)
mylist=["i am","i,heart,rock,music","i-dig-apples-and-berries","oh_my_goodness"]
wordcount(mylist)
When you do return a
, you exit the function at the first for
iteration.
You can use a list
to accumulate results:
def wordcount(mylist): #define a wordcount func
ret = [] # list to accumulate results
for i in mylist: # create a first loop to iterate the list
for c in "-,\_.": #create a sec loop to iterate the punctuation
i=i.replace(c," ") # replace the punctuation with space
a=len(i.split()) #split the str with space and calculate the len
ret.append(a) # append to list
return ret # return results
or use yield
instead of return
(it will create a generator ):
def wordcount(mylist): #define a wordcount func
for i in mylist: # create a first loop to iterate the list
for c in "-,\_.": #create a sec loop to iterate the punctuation
i=i.replace(c," ") # replace the punctuation with space
a=len(i.split()) #split the str with space and calculate the len
yield a
In order to get all the items from a generator, convert it to list
:
list(wordcount(mylist))
