Question

Given:

a variable current_members that refers to a list, and
a variable member_id that has been defined.
Write some code that assigns True to a variable is_a_member if the value associated with member_id can be found in the list associated with current_members, but that otherwise assigns False to is_a_member. Use only current_members, member_id, and is_a_member.

Answer 1

Python Code:-

#creating a list

current_members = [4, 6, 9]

#defining the variable

#assigning the value

member_id = 9

#defining variable count

count = 0

#defining the variable and setting initial value to true

is_a_member = False

#for loop is used to iterate over the list

for x in current_members:

#if statement will check whether the element is found

if x == member_id:

#set the value to true if the value is matched

is_a_member = True

#set the value to 1

count = 1

#if count == 0

#set the value of is_a_member variable to false

if count == 0:

is_a_member = False

#print the current value stored in is_a_member variable

print(is_a_member)

Explanation:

In the above python program, a list is created that is "current_members" and some values are inserted. In the next line, a three-variable is defined that are member_id, count, and is_a_member.

• In both variable member_id, count assigns some value. and in is_a_member variable assign a False value.
• Using a for loop to iterate over the list.
• Inside the loop, If the statement will check whether the element is found. Then set the value of is_a_member variable to True and count to 1.
• Another if the statement is used which checks the value of the count variable. If the value of count is 0 then set the value of is_a_member to False.
• print() function is used to display the current value of is_a_member variable.
