It's hardly Python's problem if an engineer is worried about some VB not
being there in its current form in the future. The sample code upthread
seemed gibberish to me - anybody capable of learning *that* should be
*able* to also learn Python, and then the input parsing business is not
only simple but also flexible, as already demonstrated by others. The
following assumes that the author of the code knows the desired types,
and does not assume a working DWIM feature. I wouldn't name things quite
like that in real code.
from io import StringIO
def funcall(f, x):
return f(x)
def Input(source, *dims):
return tuple(map(funcall, dims, next(source).split()))
def Vector(dim, times):
return tuple([dim] * times)
N020SdotTXT = ''' 10 6 1
8.65 0.2192347 3.33E-4 44 0.0051 6
9
1
2 1
3 '''
Number8 = StringIO(N020SdotTXT)
ND, NIN, NT = Input(Number8, int, int, int)
DINCOL = Input(Number8, *Vector(float, NIN))
[NINE] = Input(Number8, int)
[ONE] = Input(Number8, float)
TWO = Input(Number8, float, int)
[THREE] = Input(Number8, str)
Hash = dict
print('ND = {}, NIN = {}, NT = {}'.format(ND, NIN, NT),
DINCOL,
Hash(NINE = NINE, ONE = ONE, TWO = TWO, THREE = THREE),
sep = '\n')
# Output:
# ND = 10, NIN = 6, NT = 1
# (8.65, 0.2192347, 0.000333, 44.0, 0.0051, 6.0)
# {'NINE': 9, 'TWO': (2.0, 1), 'ONE': 1.0, 'THREE': '3'}
