write a program that extract words starting with Vowel From A list

# initializing list 
test_list = ["have", "a", "good", "one"] 

# printing original list 
print("The original list is : " + str(test_list)) 

res = [] 
vow = "aeiou"
for sub in test_list: 
    flag = False

    # checking for begin char 
    for ele in vow: 
        if sub.startswith(ele): 
            flag = True 
            break
    if flag: 
        res.append(sub) 

# printing result  
print("The extracted words : " + str(res)) 

write a program to replace vowels by next vowel using list comprehension + zip()

test_str = 'helloworld'
print("The original string is : " + str(test_str)) 
vow = 'a e i o u'.split() 
temp = dict(zip(vow, vow[1:] + [vow[0]])) 
res = "".join([temp.get(ele, ele) for ele in test_str]) 
print("The replaced string : " + str(res)) 

write a program to reverse words of string

def rev_sentence(sentence):  
    words = sentence.split(' ')  
    reverse_sentence = ' '.join(reversed(words))  
    return reverse_sentence  

if __name__ == "__main__":  
    input = 'have a good day'
    print (rev_sentence(input)) 

write a program to find the least Frequent Character in String

test_str = "helloworld"
print ("The original string is : " + test_str) 
all_freq = {} 
for i in test_str: 
    if i in all_freq: 
        all_freq[i] += 1
    else: 
        all_freq[i] = 1
res = min(all_freq, key = all_freq.get)  

print ("The minimum of all characters in the given word is : " + str(res)) 

write a program to find the most frequent element in a list

def most_frequent(List): 
    counter = 0
    num = List[0] 

    for i in List: 
        curr_frequency = List.count(i) 
        if(curr_frequency> counter): 
            counter = curr_frequency 
            num = i 

    return num 

List = [2, 1, 2, 2, 1, 3] 
print(most_frequent(List)) 

write a program insert character after every character pair

# initializing string  
test_str = "HellowWorld"

print("The original string is : " + test_str) 
res = ', '.join(test_str[i:i + 2] for i in range(0, len(test_str), 2)) 

print("The string after inserting comma after every character pair : " + res) 

write a program to remove i-th indexed character from a string

def remove(string, i):  

    a = string[ : i]  
    b = string[i + 1: ] 
    return a + b 

# Driver Code 
if __name__ == '__main__': 

    string = "HellowWorld"

    # Remove nth index element 
    i = 5

    # Print the new string 
    print(remove(string, i))
