如何将列表循环到变量并在循环外打印值？

Question

I am trying to loop through a list and make a variable that contains the list + some other info to be able to use it outside the for loop, however when I print my variable outside the loop I only get the last item in the list. I want to see all of them in the list.

#!/usr/bin/python
a = ['apple', 'orange', 'peanut']
for item in a:
    mylist = '*' + item
    print item

print "------out of loop ----------"
print mylist

The output is:

apple
orange
peanut
------out of loop ----------
*peanut

Answer 1

you have to declare mylist outside of the loop. also you need to use '+=' (append) to keep adding onto mylist

a = ['apple', 'orange', 'peanut']
mylist = ''
for item in a:
    mylist += '*' + item
    print(item)

print("------out of loop ----------")
print(mylist)

this output should be :

apple
orange
peanut
------out of loop ----------
*apple*orange*peanut

Answer 2

With mylist = '*' + item you always overwrite the old value of mylist

If you want to keep it, you should do something like mylist = mylist + '*' + item , depending on what you want to display

Or a different solution would be mylist += '*' + item
