There is a list from the user:

user_list = [1, 3.5, "xx", "gg", 6, "2"].
new_list = []

How to make it so that with the help of "list comprehension" from user_list to new_list moved:

1. Value with type (float)
2. Even number with type(int)
3. All elements that have type (str) turned into -2 and were sent to a new_list

CodePudding user response：

not a good way to achive result but, using list comprehension

>>> user_list = [1, 3.5, "xx", "gg", 6, "2"]                  
>>> new_list = [*[i for i in user_list if type(i)==float], *[i for i in user_list if type(i)==int], *[-2 for i in user_list if type(i)==str]]
>>> new_list
[3.5, 1, 6, -2, -2, -2]

CodePudding user response：

Using one list comprehension, this should give you new_list :

new_list = [(lambda x : -2 if type(x)==str else x)(x) for x in user_list if ((type(x)==float) or (type(x)==int and x%2==0) or (type(x)==str))]

As others have mentioned, a list comprehension is probably not the standard way to compute this result.
