There are fewer than 30 students in the A-level mathematics class. One half of them
1 answer:
The number of students that play hockey is 7
The proportion is given as:
The total number of students must be a multiple of 2, 4 and 7 less than 30;
The only multiple of 2, 4 and 7 less than 30 is 28.
The number of students that play hockey is the product of 28 and the proportion that plays hockey.
So, we have:
Multiply
Hence, 7 students play hockey

Answer:
Code is given below along with explanation and output.
Step-by-step explanation:
we can use the method of list comprehension to achieve the given task.
In a list comprehension, we create a sub-list of elements which satisfy specific conditions. the condition i !=x makes sure that x would be excluded in the modified list.
def remove_all(L, x):
return [i for i in L if i != x]
L = [1, 2, 3, 4, 5, 6, 4, 3, 2, 4 ]
print('Before =',L)
L = remove_all(L, 4)
print('After =',L)
Output:
Before = [1, 2, 3, 4, 5, 6, 4, 3, 2, 4]
After = [1, 2, 3, 5, 6, 3, 2]
As you can see we have successfully removed the multiple occurrence of x=4 while preserving the order of the list.
