Lists Code

• Please solve the following questions using Python code.  

Question-1

Prompt the user for a name and store each character of the name as a lowercase letter in a list, avoiding the use of the list() method.

Solution

name = input('Enter your name: ')

char_list = []

for i in name:
  char_list.append(i.lower())

print(f'Letters: {char_list}')

Sample Output
Enter your name: Amelia
Letters: [‘a’, ‘m’, ‘e’, ‘l’, ‘i’, ‘a’]

Question-2

Prompt the user for comma-separated numbers and store them in a list, where each number is treated as an element with a data type of float.

• Use only one input function and make use of the split() method for string parsing.

Solution

numbers = input('Enter numbers in a comma separated form: ')

number_list_str = numbers.split(',')
number_list_float = []

for i in number_list_str:
  number_list_float.append(float(i))

print(f'Numbers in list as float: {number_list_float}')

Sample Output
Enter numbers in a comma separated form: 3,8,5,1,7
Numbers in list as float: [3.0, 8.0, 5.0, 1.0, 7.0]

Question-3

Use a for loop to identify numbers in the number_list that are divisible by 5 and greater than 23, storing them in a new list named five_list.

number_list = [58, 82, 9, 25, 11, 36, 43, 27, 95, 75]

Solution

number_list = [58, 82, 9, 25, 11, 36, 43, 27, 95, 75]

five_list = []

for i in number_list:
  if i%5==0 and i>23:
    five_list.append(i)

print(five_list)

Output
[25, 95, 75]

Question-4

Use a for loop to reverse the elements of char_list and store them in a new list named reverse_list, without using any reverse method or indexing step.

char_list = ['k', 'p', 'f', 'l', 'j', 'l', 'u', 'g', 't', 'a']

Solution-1

char_list = ['k', 'p', 'f', 'l', 'j', 'l', 'u', 'g', 't', 'a']

reverse_list = []

for i in range(1,len(char_list)+1):
  reverse_list.append(char_list[-i])

print(reverse_list)

Output
[‘a’, ‘t’, ‘g’, ‘u’, ‘l’, ‘j’, ‘l’, ‘f’, ‘p’, ‘k’]

Solution-2

char_list = ['k', 'p', 'f', 'l', 'j', 'l', 'u', 'g', 't', 'a']

reverse_list = []

for char in char_list:
    reverse_list.insert(0, char)

print(reverse_list)

Output
[‘a’, ‘t’, ‘g’, ‘u’, ‘l’, ‘j’, ‘l’, ‘f’, ‘p’, ‘k’]

Solution-3

char_list = ['k', 'p', 'f', 'l', 'j', 'l', 'u', 'g', 't', 'a']

reverse_list = [char_list[-i] for i in range (1,len(char_list)+1)]

print(reverse_list)

Output
[‘a’, ‘t’, ‘g’, ‘u’, ‘l’, ‘j’, ‘l’, ‘f’, ‘p’, ‘k’]

Question-5

Use the split method to identify words in the given text that start with ‘o’ or ‘O’ excluding ‘of,’ ‘or,’ and ‘on.’

• Store the identified words in a tuple named o_tuple.

• Print the first five elements of this tuple.

print('-'*7)
print(f'|{number_list[3]}|{number_list[4]}|{number_list[5]}|')
print('-'*7)
print(f'|{number_list[6]}|{number_list[7]}|{number_list[8]}|')
print('-'*7)

Solution-2

• for loop solution

import random
number_list = list(range(1,10))
random.shuffle(number_list)

for i in range(3):
  print('-'*7)
  for j in range(3):
    print(f'|{number_list[3*i+j]}', end='')
  print('|')
print('-'*7)

Question-12

Create a list of length 10 with values randomly chosen from ‘P’ or ‘N’, where ‘P’ represents positive and ‘N’ represents negative test results.

• Use either the random module or numpy.random.

• Construct a new list replacing ‘N’ with 0 and ‘P’ with 1.

• Example

  • old_list   = [‘M’, ‘F’, ‘M’, ‘M’, ‘F’, ‘M’, ‘F’, ‘M’, ‘M’, ‘F’]

  • new_list = [ 1  ,  0 ,  1 ,  1 ,  0 ,  1 ,  0 ,   1 ,   1 , 0]

Solution

import numpy as np
old_list = np.random.choice(['P', 'N'], 10)
new_list = []

for i in old_list:
  if i == 'P':
    new_list.append(1)
  else:
    new_list.append(0)

print('Old List:', old_list)
print('New List:', new_list)

Sample Output
Old List: [‘N’ ‘N’ ‘N’ ‘P’ ‘P’ ‘P’ ‘N’ ‘N’ ‘P’ ‘P’]
New List: [0, 0, 0, 1, 1, 1, 0, 0, 1, 1]

Question-13

For the given list, identify the maximum and minimum elements. Then, subtract the minimum value from each element in the list and divide the result by the difference between the maximum and minimum elements.

• Example: given list is [3, 8, 2, 9, 4, 12, 5]

• maximum value = 12, minimum value = 2

• subtract 2 from each element: [1, 6, 0, 7, 2, 10, 3]

• divide each element by max - min = 12 - 2 = 10

  • output: [0.1, 0.6, 0, 0.7, 0.2, 1, 0.3]

number_list = [3, 8, 2, 9, 4, 12, 5]

Solution-1

number_list = [3, 8, 2, 9, 4, 12, 5]

max_value = max(number_list)
min_value = min(number_list)

result = [(i-min_value)/(max_value-min_value) for i in number_list ]
print(result)

Output
[0.1, 0.6, 0.0, 0.7, 0.2, 1.0, 0.3]

Solution-2

number_list = [3, 8, 2, 9, 4, 12, 5]

max_value = max(number_list)
min_value = min(number_list)

number_list2 = []
for i in number_list:
  number_list2.append(i-min_value)

number_list3 = []
for i in number_list2:
  number_list3.append(i/(max_value-min_value))

print(number_list3)

Output
[0.1, 0.6, 0.0, 0.7, 0.2, 1.0, 0.3]

Question-14

For the given list, calculate the mean and standard deviation.

Solution

char = input('Please enter a character:')
count = 0
index_list = [] 

for i in text:
    if i == char:
        count +=1
        if len(index_list) == 0:
          index_list.append(text.find(char))
        else:
          index_list.append(text.find(char, index_list[-1]+1))

print(f'Number of {char} is {count}.')
print(f'First 5 indexes: {index_list[:5]}')

Sample Output
Please enter a character: k
Number of k is 174.
First 5 indexes: [16, 34, 58, 72, 135]

Question-16

Generate a list containing randomly generated five-letter strings, with a length of 10.

• Use the random.choice() function for the construction of the list.

Solution

import string
import random

list5 = []

for i in range(10):
  random_word = ''
  for j in range(5):
    random_word += random.choice(string.ascii_lowercase)
  list5.append(random_word)
print(list5)

Sample Output
[‘zygmd’, ‘lbdho’, ‘osaal’, ‘moeiw’, ‘wdekx’, ‘bbzfh’, ‘auhkm’, ‘lqvep’, ‘xfcaq’, ‘ttbcc’]
