Question

1.Write a function which takes a string that contains two words separated by any amount of whitespace, and returns a string in which the words are swapped around and the whitespace is preserved. Hint: use regular expressions where \s detects the whitespaces in a string.

Example: given "Hello     World", return
"World         Hello"

2.Pandas exercises:

Write a python program using Pandas to create and display a one-dimensional array-like object containing an array of data.

Write a python program using Pandas to convert a Panda module Series to Python list and print it's type. (Hint: use ds.tolist() to convert the pandas series ds to a list)

Create a pandas dataframe called my_df with index as integer numbers between 0 to 10, first column (titled "rnd_int") as 10 integer random numbers between 10-25, second column ("rnd_float") as 10 random continuous numbers (not necessarily integer) between 15-40, and third column ("rnd_strBool") as 10 random string values that are either "True" or "False" (Hint: numpy.random.uniform(a,b,count) and numpy.random.randint(a,b,size=count) can be helpful)

Answer 1

1.

def swap(line): # Function that will swap words of string 
  
    # splitting the string into words
    words = line.split(' ')  
  
    # then reverse the splitted words and attach the whitespace
    swapped_words = ' '.join(reversed(words))  
  
    #return the new swapped string 
    return swapped_words   
  
input = 'Hello   world'
print (swap(input) )
