1. 过滤列表+大写

      1. names = ['jerry', 'hansen', 'qianan', 'Wendy', 'Tom', 'Bob']
      2. zxc = list(map(lambda x: x.upper(), filter(lambda x: len(x) > 3, names)))
      3. print(zxc)

    2. 奇偶列表

      print([(x, y) for x in range(0, 5, 2) for y in range(1, 5, 2)])

    3. 去重+首字母大写

      names = ['Bob', 'JOHN', 'alice', 'bob', 'ALICE', 'James', 'Bob', 'JAMES', 'jAMeS']
res = list(set(map(lambda x: x.capitalize(), names)))
print(res)
