Exercise 9.2.9: Strings To Integers5 points

Answer 1

Answer:

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.
