numbers = [1, 2, 3, 4] numbers_str = ', '.join(map(str, numbers)) print(numbers_str) # 输出: 1, 2, 3, 4 在这个例子中,map函数用于将numbers列表中的每个整数转换为字符串,然后使用join方法连接它们。 四、应用场景 生成CSV格式的字符串 ...
```python list_of_numbers = [1, 2, 3, 4, 5] single_string = " ".join(str(num) for num in list_of_numbers) print(single_string) # 输出:1 2 3 4 5 ``` 在这个例子中,我们使用一个生成器表达式和一个空格作为分隔符,将整数列表中的元素连接成一个单一的字符串。注意,我们使用了str()...
