Exercise 9.2.9: Strings To Integers5 points
Make a function called safe_int that takes a single argument. This function should try to convert the argument into an integer. If this succeeds, the function should return that integer. Otherwise, the function should return 0.

Then, use this function in a list comprehension to create a list out of the given list. The new list should contain either a 0 or the correct integer in place of every string in the given list:

[0, 2, 7, 0]
Make sure to print out the resulting list.

This is my code so far(i dont know what's wrong with it):
list_of_strings = ["a", "2", "7", "zebra"]

# Your code here...
def safe_int():
list = [int(x) if x. isdigit() else 0 for x in list_of_strings]
print list

safe_int()

but its asking "Function "safe_int" should take exactly 1 argument" and "You should use safe_int in a list comprehension", i dont know how to fix this code please help

x=input("Enter a String")

def safe_int(x):

   #lis1=[ int(x)if x.isdigit() else 0 for x in list_of_strings]

   lis1=[]

   lis1=x.split()

   print(lis1)

   flag=0

   j=0

   while(j in range(len(lis1))):

       if(lis1[j].isdigit()):

           flag==0

       else:

           flag==1

           try:

               if(int(lis1[j])):

                   lis1[j]=int(lis[j])

               else:

                   flag==1

                   break

           except:

               print("Cannot convert to integer")

       j+=1

   print(lis1)    

safe_int(x)

Explanation:

We are taking as an input a sentence, and then splitting it into various list items, and storing them in a list. Now we try to convert each item to integer and using try-except print the message cannot convert if its not possible or else converts it. As a check. enter 0 2 7 0   and also try Hello World.

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
