注意,iterable中必须全部是字符串类型,否则报错。如果你还是python的初学者,还不知道iterable是什么,却想来看看join的具体语法,那么你可以暂时将它理解为:字符串string、列表list、元组tuple、字典dict、集合set。当然还有生成器generator等也可以用该方法。1)字符串L='python''_'.join(L)'p_y_t_h_o_n''_uu_'...

You can also use list comprehension and theenumerate()function to remove multiple elements from a list.Enumerate()function is a built-in function provided by Python. It takes an iterable object such as alist,tuple,set,string, anddictionaryand returns enumerate object. This function automatically r...
This only works for lists of hashable values, but that includes quite a few values: strings, numbers, and most tuples are hashable in Python.You might have noticed that the order of the original items was lost once they were converted to a set:>...

Here, we have a list of tuples and we need to remove the given character from the first element of the tuple from each tuple of the list in Python.
(mylist[-1])new_tuple=tuple(mylist)# Example 5: Using filter() function# Remove the last element from the tuplenew_tuple=tuple(filter(lambdax:x!=mytuple[-1],mytuple))# Example 6: Using lists# Convert the tuple to a listmylist=list(mytuple)mylist.pop()new_tuple=tuple(mylist)...
List的Remove()根据下标删除指定元素不生效 这个方法在源码里是根据指定下标删除 而这个方法是根据指定元素删除 按ctrl进入remove方法看是那个方法,如果是图2那么肯定是不会删除成功的 所以即使你传入的是int类型的参数 ,也是不会根据指定下标删除成功的 所以把int类型的参数在转一次,就行了 最终目的是进入源码调的是...
元组(tuple):在Python中,元组是一个可以包含多个值的数据结构。在这段代码中,return 0, head和return i+1, (head, head.next)[i+1 == n]都返回了一个元组。元组的创建不需要使用括号,也就是说,当你看到由逗号分隔的值时,Python会把它理解为元组。
