1.Which expression correctly removes all empty strings from a list of strings text?
[s.notempty() for s in text]
[len(s)>0 for s in text]
[s for s in text if s]
2. Variable data is a list. Which of the following code fragments produce the same value of the variable result? (Select both.)
i = 0; result = []
while i < len(data):
if data[i].foobar() == True:
print(data[i])
i += 1
[item for item in data if item.foobar()]
result = 0
for item in data:
if item.foobar() == True:
result += item
result = []
for item in data:
if item.foobar():
result.append(item)
3. Which of the following can be X in the following code fragment? (Check all that apply.)
for foo in X:
bar(foo)
tuple()
bool()
int()
list()
str()
[s.notempty() for s in text]
[len(s)>0 for s in text]
[s for s in text if s]

Explanation / Answer
#include<iostream>
#include<conio.h>
using namespace std;
// Class Declaration
class prime
{
//Member Varibale Declaration
int a,k,i;
public:
prime(int x)
{
a=x;
}
// Object Creation For Class
void calculate()
{
k=1;
{
for(i=2;i<=a/2;i++)
if(a%i==0)
{
k=0;
break;
}
else
{
k=1;
}
}
}
void show()
{
if(k==1)
cout<<" "<<a<<" is Prime Number.";
else
cout<<" "<<a<<" is Not Prime Numbers.";
}
};
//Main Function
int main()
{
int a;
cout<<"Enter the Number:";
cin>>a;
// Object Creation For Class
prime obj(a);
// Call Member Functions
obj.calculate();
obj.show();
getch();
return 0;
}
