只要在join() 函数中加入类型转换,将数字转换为 string 型即可。 代码示例如下: nums=[1,2,3.6] numsStr=''.join(str(e) for e in nums) print(numsStr) 运行结果为: 123.6 (3)除了用 Python 的函数,我们还可以应用自定义的函数。 比如,下面的代码先定义了一个convert() 函数,如果字母是 a 或 A,...
在Python中,如何将一个列表中的所有元素添加到一个字符串中? A. string = ' '.join(list) B. string = ' '.join(item for item in list) C. string = reduce(lambda x, y: x + y, list) D. string = ''.join(list) 相关知识点: ...
In Python, joining a list of strings involves concatenating the elements of the list into a single string, using a specified delimiter to separate each element. This operation is particularly useful when you need to convert a list of strings into a single string, such as when you want to sa...
对于上面代码中的变量list_1,dict_1,a都是可迭代对象。我们for循环它们,就可以拿到一个值,然后再将这个值进行相应的处理就ok # 比如 "--".join(list_1)这个操作,它的输出为"1--2--3--4",一个字符串 list_1 = ["1","2","3","4"] param = "--" res = "" for i in range(len(list_1...
Python中二维数组string转list join 在Python中,我们经常会遇到需要将二维数组(也称为列表的列表)中的字符串元素转换为列表并进行拼接操作的需求。这个过程需要涉及到字符串的分割和列表的拼接,下面我们来详细介绍一下这个过程。 二维数组string转list 首先,我们需要将二维数组中的字符串元素转换为列表。在Python中,我们...

The string join() method returns a string by joining all the elements of an iterable (list, string, tuple), separated by the given separator. Example text = ['Python', 'is', 'a', 'fun', 'programming', 'language'] # join elements of text with space print(' '.join(text)) # ...
