Question

1. Find and print the length of the list listTest.

2. We can test if an item exists in a list or not, using the keyword in

It will give you a boolean response if a certain element is present. Find whether 'p' or 'P' is present in listTest, and print the results.

Print results first for 'p' and then for 'P' as shown in example below.

For example:

Test	Result
listTest=['c','i','s','c','1','0','6','P','y','t','h','o','n']	False True

3. We can delete one or more items from a list using the keyword del. It can even delete the list entirely.

From the list listTest, delete the 4th element.

4. Using the del keyword and/or the slicing operator :, delete the 3rd to 6th elements from the list listTest.

5. We can access a range of items in a list by using the slicing (colon) operator.

There is a predefined list listTest. Use the slicing operator to print the third to fifth elements from listTest as a list.

Note: this does not mean the values at indices 3, 4, and 5!

6. We can access a range of items in a list by using the slicing operator (colon).

7. There is a predefined list listTest. Use the slicing operator to print the elements (as a list) from beginning through the sixth from listTestWe can access a range of items in a list by using the slicing operator (colon).

Given a predefined list listTest, use slicing to print the elements from the fourth through the end from listTest

Answer 1

listTest=["C","i","s","c","1","0","6","P","y","t","o","n"]#defining a list
# 1.legth of list
print("1.Legth of list = ",len(listTest))#len operator is used to find length of list

# 2.using keyword in
print("2.")
if 'p' in listTest:
print("True")
else:
print("False")
if 'P' in listTest:
print("True")
else:
print("False")

# 3.deleting 4th element
del(listTest[3]) #list index is starts from 0.so here 3 means 4th element
print("3.After deleting 4th element:\n",listTest)

# 4.deleting 3 to 6 elements
del(listTest[2:6])#[2:6] means 3rd,4th,5th,6th elements
print("4.After deleting 3 to 6 elements:\n",listTest)

# 5.prints 3 to 5 elements from listTest as list
list1=listTest[2:5] #[2:5] means 3rd,4th,5th elements
print("5.prints 3 to 5 elements:\n",list1)

# 6.accessing rage of items in listTest
print("6.accessing 1 to 4 elements:\n",listTest[:4])#[:4] means 1st,2nd,3rd,4th elements

# 7.
print("7.")
print("Beginning through the sixth:\n",listTest[:6]) # [:6] means 1st element to 6th element
print("fourth through the end:\n",listTest[3:]) # [3:] means 4th element to last element
