Here, I have the list test_list=[1,2,3,0,5].
I want to change the list which contains empty values, like [1,2,3, ,5]
All the way I found is to add None or np.nan or just ''.
But all those values are not working at my case, cause I just need to leave the place empty. how can I create it? The reason I need it is to put those values into scipy's interpolation.
Umm.. maybe yes. I just need the list which will be printed as [1, 2, 3, ,5] in this format...
You can define a class with a repr() of the empty string:
>>> class Nothing:
... def __repr__(self):
... return ''
...
>>> l = [1, 2, 3, Nothing(), 5]
>>> l
[1, 2, 3, , 5]
You can't just "not have" a value in a list, a list is defined by its items. You could use None which is Python's representation of "nothing" or [].
If you just want to print an array and ignore None values you can make a function.
numbers = [1,2,3,4,None,5,6,7,8,9,10]
def print_list(input_list):
printstr = "["
for item in input_list:
item = item if item else ""
printstr += str(item) + ","
printstr += "]"
print(printstr)
print_list(numbers)
# prints [1,2,3,4,,5,6,7,8,9,10]
None?[1, 2, 3, ,5]?
