Python Programs on Strings:

1. Write a Python program to check if a string is numeric.
Ans.
str = 'a123'
#str = '123'
try:
    i = float(str)
except (ValueError, TypeError):
    print('\nNot numeric')
print()
 
2. Write a Python program to check if lowercase letters exist in a string.
Ans.  
str1 = 'A8238i823acdeOUEI'
print(any(c.islower() for c in str1))
 
3. Write a Python program to count the number of characters (character frequency) in a string.
Ans.
def c(str1):
    dict = {}
    for n in str1:
        keys = dict.keys()
        if n in keys:
            dict[n] += 1
        else:
            dict[n] = 1
    return dict
print(c(' simplycoding.in'))
 
4. Write a Python program to count the occurrences of each word in a given sentence.
Ans.
def word_count(str):
    counts = dict()
    words = str.split()
 
    for word in words:
        if word in counts:
            counts[word] += 1
        else:
            counts[word] = 1
 
    return counts
 
print( word_count('the quick brown fox jumps over the lazy dog.'))
 
5. Write a Python script that takes input from the user and displays that input back in upper and lower cases.
Ans.
user_input = input("What's your favourite language? ")
print("My favourite language is ", user_input.upper())
print("My favourite language is ", user_input.lower())
 
6. Write a Python program to count and display the vowels of a given text.
Ans.
def vowel(text):
    vowels = "aeiuoAEIOU"
    print(len([letter for letter in text if letter in vowels]))
    print([letter for letter in text if letter in vowels])
vowel('Welcome To Simply Coding');
 
7. Write a Python program to remove spaces from a given string.
Ans.
def remove_spaces(str1):
  str1 = str1.replace(' ','')
  return str1
   
print(remove_spaces("Welcome To Simply Coding"))
print(remove_spaces("a b c")) 
 
8. Write a Python program to capitalize first and last letters of each word of a given string.
Ans.
def capitalize_first_last_letters(str1):
     str1 = result = str1.title()
     result =  ""
     for word in str1.split():
        result += word[:-1] + word[-1].upper() + " "
     return result[:-1] 
    
print(capitalize_first_last_letters("hello world"))
print(capitalize_first_last_letters("Simply coding"))
