return False
for i in range(2, int(n**0.5)+1):
if n % i == 0:
return False
return True- Sum of digits in a number:
def sum_of_digits(n):
sum = 0
while n > 0:
sum += n % 10
n //= 10
return sum- Check if a string is a pangram:
import string
def is_pangram(s):
s = s.lower()
alphabet = set(string.ascii_lowercase)
return set(s) >= alphabet
print(is_pangram(“The quick brown fox jumps over the lazy dog”))
- Find the largest element in a list:
def largest_element(lst):
return max(lst)- Find the second largest element in a list:
def second_largest_element(lst):
sorted_lst = sorted(lst, reverse=True)
return sorted_lst[1]- Find the frequency of each element in a list:
def frequency(lst):
freq = {}
for i in lst:
if i in freq:
freq[i] += 1
else:
freq[i] = 1
return freq- Check if a list is sorted:
def is_sorted(lst):
return all(lst[i] <= lst[i+1] for i in range(len(lst)-1))- Merge two lists:
list1 = [1, 2, 3]
list2 = [ 4, 5] merged_list = list1 + list2 print(merged_list)
16. Remove duplicates from a list:lst = [1, 2, 3, 1, 2, 1]
unique_lst = list(set(lst))
print(unique_lst)
- Convert a string to a list:
s = "Hello World"
lst = list(s)
print(lst)
- Check if two strings are anagrams:
def is_anagram(s1, s2):
return sorted(s1) == sorted(s2)- Count the number of vowels in a string:
def count_vowels(s):
vowels = "aeiou"
count = 0
for i in s:
if i in vowels:
count += 1
return count- Check if a string is a palindrome:
def is_palindrome(s):
return s == s[::-1]- Find the largest palindrome in a string:
def largest_palindrome(s):
max_palindrome = ""
for i in range(len(s)):
for j in range(i+1, len(s)):
substr = s[i:j]
if substr == substr[::-1] and len(substr) > len(max_palindrome):
max_palindrome = substr
return max_palindrome- Sort a list of dictionaries based on a key:
lst = [{'name': 'John', 'age': 30}, {'name': 'Jane', 'age': 25}, {'name': 'Bob', 'age': 35}]
sorted_lst = sorted(lst, key=lambda x: x['age'])
print(sorted_lst)
- Convert a list of strings to lowercase:
lst = ["Hello", "WORLD"]
lower_lst = [s.lower() for s in lst]
print(lower_lst)
- Convert a list of integers to binary:
lst = [1, 2, 3, 4, 5]
binary_lst = [bin(i)[2:] for i in lst]
print(binary_lst)
- Convert a list of strings to integers:
lst = ["1", "2", "3", "4", "5"]
int_lst = [int(s) for s in lst]
print(int_lst)
- Calculate the average of a list of numbers:
lst = [1, 2, 3, 4, 5]
average = sum(lst) / len(lst)
print(average)
- Swap two variables:
a = 10
b = 20
a, b = b, a
print(a, b)
- Find the common elements between two lists:
list1 = [1, 2, 3, 4, 5]
list2 = [4, 5, 6, 7, 8]
common_elements = list(set(list1) & set(list2))
print(common_elements)
- Calculate the factorial of a number using recursion:
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n-1)- Check if a number is a power of 2:
def is_power_of_two(n):
if n == 0:
return False
else:
return n & (n-1) == 0These are just a few examples of what you can do with Python. There are countless other possibilities, and the more you learn, the more you’ll be able to do with the language.
