4. Counting Vowels in a Given Word

vowel = ['a', 'e', 'i', 'o', 'u']
word = "programming"
count = 0
for character in word:
if character in vowel:
count += 1
print(count)

> 3

5. Counting Consonants in a Given Word

vowel = ['a', 'e', 'i', 'o', 'u']
word = "programming"
count = 0
for character in word:
if character not in vowel:
count += 1
print(count)

> 8

6. Counting the Number of Occurances of a Character in a String

word = "python"
character = "p"
count = 0

7. Writing Fibonacci Series

fib = [0,1]
# Range starts from 0 by default
for i in range(5):
fib.append(fib[-1] + fib[-2])

# Converting the list of integers to string
print(', '.join(str(e) for e in fib))

> 0, 1, 1, 2, 3, 5, 8

8. Finding the Maximum Number in a List

numberList = [15, 85, 35, 89, 125]

maxNum = numberList[0]
for num in numberList:
if maxNum < num:
maxNum = num
print(maxNum)

> 125

9. Finding the Minimum Number in a List

numberList = [15, 85, 35, 89, 125, 2]

minNum = numberList[0]
for num in numberList:
if minNum > num:
minNum = num
print(minNum)

> 2

10. Finding the Middle Element in a List

numList = [1, 2, 3, 4, 5]
midElement = int((len(numList)/2))

print(numList[midElement])

> 3

11. Converting a List into a String

lst = ["P", "Y", "T", "H", "O", "N"]
string = ''.join(lst)

print(string)
print(type(string))

> PYTHON

12. Adding Two List Elements Together

lst1 = [1, 2, 3]
lst2 = [4, 5, 6]

res_lst = []
for i in range(0, len(lst1)):
res_lst.append(lst1[i] + lst2[i])
print(res_lst)

> [5, 7, 9]

13. Comparing Two Strings for Anagrams

str1 = "Listen"
str2 = "Silent"

str1 = list(str1.upper())
str2 = list(str2.upper())
str1.sort(), str2.sort()

if(str1 == str2):
print("True")
else:
print("False")

> True

14. Checking for Palindrome Using Extended Slicing Technique

str1 = "Murali".lower()
str2 = "murali".lower()

if(str1 == str2[::-1]):
print("True")
else:
print("False")

> True

15. Counting the White Spaces in a String

string = "P r ogramm in g "
print(string.count(' '))

> 5

16. Counting Digits, Letters, and Spaces in a String

# Importing Regular Expressions Library
import re

name = 'Python is 1'

digitCount = re.sub("[^0-9]", "", name)
letterCount = re.sub("[^a-zA-Z]", "", name)
spaceCount = re.findall("[ \n]", name)

print(len(digitCount))
print(len(letterCount))
print(len(spaceCount))

> 1
> 8
> 2

17. Counting Special Characters in a String

# Importing Regular Expressions Library
import re
spChar = "!@#$%^&*()"

count = re.sub('[\w]+', '', spChar)
print(len(count))

> 10

18. Removing All Whitespace in a String

import re

string = "C O D E"
spaces = re.compile(r'\s+')
result = re.sub(spaces, '', string)
print(result)

> CODE

19. Building a Pyramid in Python

floors = 3
h = 2*floors-1
for i in range(1, 2*floors, 2):
print('{:^{}}'.format('*'*i, h))

> *
***
*****

20. Randomizing the Items of a List in Python

from random import shuffle

lst = ['Python', 'is', 'Easy']
shuffle(lst)
print(lst)

> ['Easy', 'is', 'Python']
