Python: Capitalize first and last letters of each word of a given string
Python String: Exercise-60 with Solution
Write a Python program to capitalize first and last letters of each word of a given string.
Sample Solution-1:
Python Code:
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("python exercises practice solution"))
print(capitalize_first_last_letters("w3resource"))
Sample Output:

Sample Solution-2:
Capitalizes the first letter of a string.
- Use list slicing and str.upper() to capitalize the first letter of the string.
- Use str.join() to combine the capitalized first letter with the rest of the characters.
- Omit the lower_rest parameter to keep the rest of the string intact, or set it to True to convert to lowercase.
Python Code:
def capitalize_first_letter(s, lower_rest = False):
return ''.join([s[:1].upper(), (s[1:].lower() if lower_rest else s[1:])])
print(capitalize_first_letter('javaScript'))
print(capitalize_first_letter('python', True))
Sample Output:

Python: Tips of the Day
Check if a given key already exists in a dictionary:
In is the intended way to test for the existence of a key in a dict.
d = {"key1": 10, "key2": 23} if "key1" in d: print("this will execute") if "nonexistent key" in d: print("this will not")
If you wanted a default, you can always use dict.get():
d = dict() for i in range(100): key = i % 10 d[key] = d.get(key, 0) + 1
and if you wanted to always ensure a default value for any key you can either use dict.setdefault() repeatedly or defaultdict from the collections module, like so:
from collections import defaultdict d = defaultdict(int) for i in range(100): d[i % 10] += 1
but in general, the in keyword is the best way to do it.
