How to remove square brackets for each item from a list [duplicate]

Question

Excel has a list of numbers, I am expecting to see something like this:

[110652450, 5309154]

However I see something like this:

[[110652450], [5309154]] 

I tried newtest = [x[:-1] for x in df] suggested on a similar question but that just removes my numbers and keeps the braquets

df = pd.read_excel(filename.xlsx",sheetname='Sheet1')


df = df.values.tolist()

print(df)

Answer 1

I didn't quite get your question, but you seem to be looking for something like this?

df = [[110652450], [5309154]]
newest = [i[0] for i in df]
print(newest)
>> [110652450,5309154]

Answer 2

numpy.squeeze might be the preferred method to do this. Call np.squeeze(a) for the array that you wish to flatten. np.squeeze should be much faster than a list comprehension such as [e[0] for e in a]
