56. 检查字符串是否只包含数字

s = "12345"
print(s.isdigit())

57. 找到列表中出现次数最多的元素

from collections import Counter
lst = [1, 2, 2, 3, 4, 4, 4, 5]
counter = Counter(lst)
print(counter.most_common(1)[0][0])

58. 计算字符串中的元音数

def count_vowels(s):
    vowels = "aeiouAEIOU"
    return sum(1 for char in s if char in vowels)

s = "hello world"
print(count_vowels(s))

59. 计算字符串中的辅音数

def count_consonants(s):
    vowels = "aeiouAEIOU"
    return sum(1 for char in s if char.isalpha() and char not in vowels)

s = "hello world"
print(count_consonants(s))

60. 找到字符串中的最长单词

def longest_word(s):
    words = s.split()
    return max(words, key=len)

s = "Find the longest word in this sentence"
print(longest_word(s))
