If you have not solved the above exercises, please complete them to understand and practice each topic in detail. After that, you can solve the below questions quickly.

Exercise 1: Reverse each word of a string

Expected Output

  • Use the split() method to split a string into a list of words.
  • Reverse each word from a list
  • finally, use the join() function to convert a list into a string

Steps to solve this question :

  • Split the given string into a list of words using the split() method
  • Use a list comprehension to create a new list by reversing each word from a list.
  • Use the join() function to convert the new list into a string
  • Display the resultant string

Exercise 2: Read text file into a variable and replace all newlines with space

Given : Assume you have a following text file (sample.txt).

Expected Output :

  • First, read a text file.
  • Next, use string replace() function to replace all newlines ( \n ) with space ( ' ' ).

Steps to solve this question : -

  • First, open the file in a read mode
  • Next, read all content from a file using the read() function and assign it to a variable.
  • Display final string

Exercise 3: Remove items from a list while iterating

Description :

In this question, You need to remove items from a list while iterating but without creating a different copy of a list.

Remove numbers greater than 50

Expected Output : -

  • Get the list's size
  • Iterate list using while loop
  • Check if the number is greater than 50
  • If yes, delete the item using a del keyword
  • Reduce the list size

Solution 1: Using while loop

Solution 2: Using for loop and range()

Exercise 4: Reverse Dictionary mapping

Exercise 5: display all duplicate items from a list.

  • Use the counter() method of the collection module.
  • Create a dictionary that will maintain the count of each item of a list. Next, Fetch all keys whose value is greater than 2

Solution 1 : - Using collections.Counter()

Solution 2 : -

Exercise 6: Filter dictionary to contain keys present in the given list

Exercise 7: print the following number pattern.

Refer to Print patterns in Python to solve this question.

  • Use two for loops
  • The outer loop is reverse for loop from 5 to 0
  • Increment value of x by 1 in each iteration of an outer loop
  • The inner loop will iterate from 0 to the value of i of the outer loop
  • Print value of x in each iteration of an inner loop
  • Print newline at the end of each outer loop

Exercise 8: Create an inner function

Question description : -

  • Create an outer function that will accept two strings, x and y . ( x= 'Emma' and y = 'Kelly' .
  • Create an inner function inside an outer function that will concatenate x and y.
  • At last, an outer function will join the word 'developer' to it.

Exercise 9: Modify the element of a nested list inside the following list

Change the element 35 to 3500

Exercise 10: Access the nested key increment from the following dictionary
