I want to create a series of lists with unique names inside a for-loop and use the index to create the liste names. Here is what I want to do
x = [100,2,300,4,75]
for i in x:
list_i=[]
I want to create empty lists such as
lst_100 = [], lst_2 =[] lst_300 = []..
any help?
Don't make dynamically named variables. It makes it hard to program with them. Instead, use a dict:
x = [100,2,300,4,75]
dct = {}
for i in x:
dct['lst_%s' % i] = []
print(dct)
# {'lst_300': [], 'lst_75': [], 'lst_100': [], 'lst_2': [], 'lst_4': []}
Use a dictionary to hold your lists:
In [8]: x = [100,2,300,4,75]
In [9]: {i:[] for i in x}
Out[9]: {2: [], 4: [], 75: [], 100: [], 300: []}
To access each list:
In [10]: d = {i:[] for i in x}
In [11]: d[75]
Out[11]: []
And if you really want to have lst_
in each label:
In [13]: {'lst_{}'.format(i):[] for i in x}
Out[13]: {'lst_100': [], 'lst_2': [], 'lst_300': [], 'lst_4': [], 'lst_75': []}
