SUMMING THE TRIPLES OF THE EVEN INTEGERS FROM 2 THROUGH 10) Starting with a list containing 1 through 10, use filter, map and su

Anestetic [448]

Answer:

numbers=list(range(1,11)) #creating the list

even_numbers=list(filter(lambda x: x%2==0, numbers)) #filtering out the even numbers using filter()

triples=list(map(lambda x:x*3 ,even_numbers)) #calculating the triples of each even number using map

total_triples=sum(triples) #calculatting the sum

numbers=list(range(1,11)) #creating the list

even_numbers=[x for x in numbers if x%2==0] #filtering out the even numbers using list comprehension

triples=[x*3 for x in even_numbers] #calculating the triples of each even number using list comprehension

total_triples=sum(triples) #calculating the sum.

Explanation:

Go to the page where you are going to write the code, name the file as 1.py, and copy and paste the following code;

numbers=list(range(1,11)) #creating the list

even_numbers=list(filter(lambda x: x%2==0, numbers)) #filtering out the even numbers using filter()

triples=list(map(lambda x:x*3 ,even_numbers)) #calculating the triples of each even number using map

total_triples=sum(triples) #calculatting the sum

numbers=list(range(1,11)) #creating the list

even_numbers=[x for x in numbers if x%2==0] #filtering out the even numbers using list comprehension

triples=[x*3 for x in even_numbers] #calculating the triples of each even number using list comprehension

total_triples=sum(triples) #calculating the sum

What error occurs in the following program? #include using namespace std; int main() { int number1, number2, sum; cout <<

Nady [450]

Answer:

1. ‘cout’ was not declared in this scope.

2. ‘cin’ was not declared in this scope.

3. lvalue required as left operand of assignment.

Explanation:

The code gives the error cout and cin was not declare. This error means, we not include the library where they define.

cout and cin is the input/output instruction and they include in the library iostream file.

the last error is lvalue required as left operand of assignment.

lvalue means the assignable value, we actually do the wrong assignment.

number1 + number2 = sum;

here, sum is is the assignment variable. so, it must be in the right side of the '=' operator.

sum = number1 + number2 ;

Now, the above is correct. the value number1 plus number2 is assign to sum.
