Having a problem printing from a list of lists, which reads from a file;
input1,input2,input3 = eval(input())
inputList1 = []
inputList2 = []
inputList3 = []
inputListA = []
inputListB = []
inputListC = []
rootList1 = []
rootList2 = []
print(format('Coefficients','15s'),format('# of Roots','15s'),'Roots')
print('==================================================')
while (input1 != 0 and input2 != 0 and input3 != 0):
rootProc = QuadEq(input1,input2,input3)
rootS = rootProc.discRoot()
if (rootS == 0):
inputList2.append(input1)
inputList2.append(input2)
inputList2.append(input3)
inputListB.append(inputList2[:])
rootList1.append(rootProc.RootOne())
elif (rootS > 0):
inputList3.append(input1)
inputList3.append(input2)
inputList3.append(input3)
inputListC.append(inputList3[:])
rootList2.append(rootProc.RootOne())
rootList2.append(rootProc.RootTwo())
else:
inputList1.append(input1)
inputList1.append(input2)
inputList1.append(input3)
inputListA.append(inputList1[:])
input1,input2,input3 = eval(input())
for i in range(len(inputListA)):
print(format(inputListA,'5s'), format('No Real Roots','>15s'), '')
This only prints part of what I want to do, but I've been doing so as a test. what I want it to print as looks like
1 1 1 No Real Roots
9 -2 14 No Real Roots
6 2 10 No Real Roots
What I get after compiling:
[[1, 1, 1], [1, 1, 1, 9, -2, 14], [1, 1, 1, 9, -2, 14, 6, 2, 10]] No Real Roots
[[1, 1, 1], [1, 1, 1, 9, -2, 14], [1, 1, 1, 9, -2, 14, 6, 2, 10]] No Real Roots
[[1, 1, 1], [1, 1, 1, 9, -2, 14], [1, 1, 1, 9, -2, 14, 6, 2, 10]] No Real Roots
Why does it keep adding to the line?
You are appending the whole list every time.
inputList1.append(input1)
inputList1.append(input2)
inputList1.append(input3)
inputListA.append(inputList1[:]) # ouchy
You probably mean something like this:
inputListA.append(inputList1[-3:])
Either that or you mean to clear inputListN at each pass.
EDIT:
To get rid of brackets:
format(' '.join([str(i) for i in currentList]), ...)
