如何从字符串列表或混合列表中提取整数（不使用re模块）

问题2：从给定混合列表中提取整数（不使用re模块） #

For your specific list ['My', '2', 'favorite', 'numbers', 'are', '42', 'and', '69'], we can use the same logic as above—no need for regex at all. Here's the direct implementation:

mixed_list = ['My', '2', 'favorite', 'numbers', 'are', '42', 'and', '69']
result = []

for item in mixed_list:
    try:
        result.append(int(item))
    except ValueError:
        # Ignore non-integer strings
        pass

print(result)  # Output: [2, 42, 69]

This is straightforward and efficient for this use case. The try-except block is perfect here because we only care about strings that are pure integers—no partial matches or edge cases to worry about in this specific list.
