Answer:
Following are the code to this question:
l= []#defining an empty list
n=int(input("Enter total element you want to insert: "))#defining variable to input total element
for i in range(0,n):# defining loop to input value in list
insert=int(input())#defining variable insert to input value
l.append(insert) # adding the elemenents into the list
x=n//2#calculating midpoint
l1 =l[:x]#using slicing to hold first-half value in l1 list
l2 =l[x:]#using slicing to hold second-half value in l2 list
print("Before interchange: ")#print message
print ("list : ",l)#print input list
l3=l2 + l1#add value in l3
print("After interchange: ")#print message
#print(l3) #print list l3
print (str(l3)[1:-1])#print list l3
Output:

Explanation:
Description of the code:
- In the above python program, an empty list l is declared, in the next line, variable n is defined, that input the total number of the list elements. In the next line, the for loop is declared, which uses the insert variable input value and used the append method to add value in the list.
- In the next step, the variable x is declared, which finds the midpoint of the list, and defines the l1 and l2 lists, that use slicing to hold the first and second half values.
- In the last step, the l3 list is declared, that adds the l1 and l2 lists and use the print method to print its values.
Some programs that we have used that have condition-controlled loops and count-controlled loops due to the following reasons.
Explanation:
Condition-controlled loops
A program could be made more intelligent by programming it to avoid hazards. For example, if the robot vehicle is 3 cm from the edge of the table and you tell it to move forwards 5 cm, it will drive off the edge of the table. To stop this from happening, you might write a condition-controlled loop like this:
move forward
repeat until (touching table edge)
Condition-controlled loops can be used to add a high degree of intelligence to a computer system.
Count Controlled Loops
A count controlled loop is a repetition structure that iterates a specific number of times
You can write a count controlled loop using a
while() loop.
For example:
counter = 0
while counter < 5:
print (“This will print 5
times”)
counter += 1

Answer:
The very first command contains an error.
Explanation:
The create query is used to create the table in the database. The syntax of the create query is :
create table tablename(column1 datatype,column2 datatype ........columnn datatype);
So there is a keyword table is missing in the given query.
so it is incorrect query.
INSERT INTO vehicletype VALUES (1,"truck","Ford",2000); This query is correct.
SELECT * FROM vehicletype; This query is also correct.
