[FIXED] How to check qTableWidget for empty cells

Issue

How to check if qTableWidget has empty cells and if has, turn those empty in 0(zero)?

With this I import data from qtablewidget table_Level_N and turn them in array array, if array has 0 - code execution stops and print out error message in textedit:

self.ui.textEdit_status_N.clear()
array = []
for i in range(self.ui.table_Level_N.rowCount()):
    row = []
    array.append(row)
    for j in range(1,6):
        item = self.ui.table_Level_N.item(i,j)
        if item:
            try:
                row.append(float(item.text()))
            except TypeError:
                row.append(0)
         else:
            row.append(0)
if np.all(array):
[some operation]
else: self.ui.textEdit_status_N.append("Error: array has zero")

Solution

add

except ValueError:
    row.append(0)

right after TypeError, it will turn all empty cells to 0
