Only one value in file, numpy.loadtxt() just returns the value instead of array?

Question

When only one value in file, numpy.loadtxt() just returns the value instead of array, how to avoid?

Thank you in advance!

e.g. there's only 12345 in a file

12345.6

numpy.loadtxt() returns

12345.6

instead of

array([12345.6])

Answer 1

Use the ndmin parameter of numpy.loadtxt. Set it to 1, and you will always have an array with at least one dimension.
