'Iterate through list to create list of lists
I have two lists: list1 and list2 such that:
list1: [‘str0’,’str1’,str2’,etc.] of len() N
list2: [‘dataframe0’,’dataframe1’,’dataframe2’,dataframe3’,etc.] of len() N
(the two lists are of the same length)
What I want to do this this:
Use both lists combined (such that index 0, 1, 2, 3, etc. for the lists are linked). (so zip() within a for loop)
I want to use the associated index ‘strX’ in renaming the columns in ‘dataframeX’.
I want to then create a new list of lists such that:
- ListA: drop index 0 from list1 and list2, but keep all other remaining objects
- ListB: drop index 1 from list1 and list2, but keep all other remaining objects
- ListC: drop index 2 from list1 and list2, but keep all other remaining objects
- Etc.
so to create a list of lists where every list represents a copy of the original list with one object removed (sequentially).
- Newlist [ListA, ListB, ListC, etc.]
I am having trouble performing this within for loops even with embedded enumerate function.
Any thoughts or guidance?
Here is the original code I was trying (which was clearly not working):
OV = []
for i, j in (zip(range(0,len(syms)), range(0,len(Results)))):
z = Results.index(Results[j])
w = Results
c = Results.copy()
x = w.index(z)
c.pop(x)
b = syms[i]
a = syms
u = syms.copy()
s = a.index(b)
u.pop(s)
r = []
for m, n in (zip(range(0,len(c)), range(0,len(u)))):
y = c[m].copy()
y.columns = [str(u[n]) + str(col) for col in y.columns]
r.append(y)
o = pd.concat(r, axis = 1)
ov = pd.concat([o, outside], axis = 1)
ove = pd.concat([z, ov], axis = 1)
OV.append(ove)
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
