For loop returning odd values
0
I have two lists I want to iterate through:
efw = [13.882352941176457, 10.854092526690406, 94.25675675675676, 17.851739788199694, 14.63844797178131, 8.166189111747846, 5.278592375366564, 3.4129692832764347, -6.413612565445015, 11.678832116788328, 23.859649122807003, 4.545454545454564, 10.105580693815996, -3.562340966921118, -0.6684491978609763, 2.285714285714291, 8.505747126436791]
and
gini = [3.9215686274509887, 6.190476190476191, -7.733812949640296, -16.608391608391603, -13.458262350936979, 7.505518763796926, -12.884615384615394, -20.21276595744681, -19.839679358717433, -10.885608856088568, -12.891986062717764, -15.56420233463035, -12.66540642722116, -12.802768166089962, -11.336032388663975, -13.507625272331147, -1.882845188284521]
I want to create two new lists with + and - depending on the values in gini and efw. If the value in gini is positive, then a + should be added to the g list. Same with the e and efw lists. I have tried:
g =
e =
for n in gini:
if n > 0:
g.append("+")
g.append("-")
for f in efw:
if f > 0:
e.append("+")
e.append("-")
But for some positive values in gini there is a - sign... Why is the for loop appending the wrong symbols to the new lists?
