I have Tkinter program that has to add a significant amount of data to the window so I tried to write a for loop to take care of it but since I have to use a string variable for the name of the object that Tkinter is running .insert() on the object. I didn't explain it very well here is the method
def fillWindow(self):
global fileDirectory
location = os.path.join(fileDirectory, family + '.txt')
file = open(location, 'r')
ordersDict = {}
for line in file:
(key, value) = line.split(':', 1)
ordersDict[key] = value
for key in ordersDict:
ordersDict[key] = ordersDict[key][:-2]
for item in ordersDict:
if item[0] == '#':
if item[1] == 'o':
name = 'ordered%s' %item[2:]
right here is the problem line because I have the variable that matches the name of the entry object already created but 'name' is actually a string variable so it gives me the error "AttributeError: 'str' object has no attribute 'insert'"
name.insert(0,ordersDict[item])
here is the entire class. It makes a Tkinter window and fills it with a sort of shipping screen so all the entries are for how many orders of a certain thing are needed. I'm also very new so I know that I do things the long way a lot.
class EditShippingWindow(Tkinter.Toplevel):
def __init__(self, student):
Tkinter.Toplevel.__init__(self)
self.title('Orders')
family = student

## Methods
def fillWindow(self):
global fileDirectory
location = os.path.join(fileDirectory, family + '.txt')
file = open(location, 'r')
ordersDict = {}
for line in file:
(key, value) = line.split(':', 1)

ordersDict[key] = ordersDict[key][:-2]
for item in ordersDict:

It looks like you have a conceptual error there: inside this method, the variable "name" does not exist up to the last line on the first listing. Then it is created, and points to an ordinary Python string -- if you are using a "name" variable elsewhere on your class that variable does not exist inside this method.
For an easy fix of your existing code, try calling the variable as "self.name" instead of just name where it is created, and on your last line in this method use:
self.name.insert(0,ordersDict[item]) instead.
The self. prefix will turn your variable into an instance variable, which is shared across methods on the same instance of the class.
On a side note, you don' t need even the dictionary much less three consecutive for loops on this method, just insert the relevant values you extract from "line" in your text variable.

above is my code using selenium to navigate the webpage with a table.
First judgement: if the current row is reviewed,
not yet reviewed? ok, print the info;
already reviewed？skip it.
then plus judgement: if there certain string "car" in the info:
no? skip;
yes, click it, the row disappear;
But currently when I am running this, the actual status is :
when doing the plus judement, if the string "car" is not in the info,
it keeps printing the info, it seems it not doing the else branch, is doing the line 6_9 in this snippet, always, dead end loop.
Why? anybody give me a clue?
to make things clear， i have simplified my code as below:
list = []
list.append("ff122")
list.append("carff")
list.append("ff3232")
list.append("ffcar")
list.append("3232")
order = 0
selected = 0
while selected < 6:
current_tr = list[order]
print("round %d %s" % (order, current_tr))
if "ff" in current_tr:
print("ff is in current_tr")
if "car" in current_tr:
print("car")
selected = selected + 1
order = order + 0
else:
order = order + 1
print("order is %d" % order)
else: # if already reviewed, order + 1
order = order + 1
print("order is %d" % order)
everybody can run this, what I need to do is firstly filter the "ff", if "ff" exists, then filter "car". both two conditions TRUE, selected +1, until selected reach certain number. in real instance, don't doubt that the list is long enough.
After concluding the first lecture of Harvard's AI course on edX, I have decided to implement the concepts taught, first being the depth-first search algorithm.
The objective of this program is to input a maze in text file mazefile and find a path from S to G using the depth-first search algorithm.
The project currently consists of 4 files, (1) the code with the class methods to operate or use the (2) text file which contains the maze, another text file (3) that contains the result file (where the AI has explored) and the main python script (4). Here they are, feel free to copy and paste these into a folder and to see how they run.

You can change the maze and its size however it must
-Respect the key above
-Have ONE Starting point and goal
-The maze must be in between 'START' and 'END'
-The maze MUST be surrounded by occupied space
SAMPLE PROBLEMS:

There is also a resultfile, however if you would just create an empty textfile with that name (no extension), the program will fill it in with results.
The problem is with the resultfile, here it is:
DEPTH FIRST SEARCH
F - Free
O - Occupied
S - Starting point
G - Goal
E - Explored/Visited
(Abdulaziz Albastaki 2020)

The AI skipped a few spaces to get to the goal, why is it doing so?
Feel free to ask me for any clarifications.
There are the following issues:
the last if block in nearbyFreeSpaces uses a wrong index:
if self.whatIs(self.currentPosition[1],self.currentPosition[1]+1) == search:
self.freeSpaces.append([self.currentPosition[1],self.currentPosition[1]+1])
should be:
if self.whatIs(self.currentPosition[0],self.currentPosition[1]+1) == search:
self.freeSpaces.append([self.currentPosition[0],self.currentPosition[1]+1])
The final position is not correctly added to the path. The last line of this block:
if len(finger.nearbyFreeSpaces("G")) == 1: #If the goal is bordering this space
result = finger.nearbyFreeSpaces("G")[0]
explored.append(finger.currentPosition)
...should be:
explored.append(result)
This is how it looks like before and after, for the problem am trying to solve using Python. I have been trying for weeks. And am failing so miserable to tell Python to do the following:
STEP1: If you find on this document: "LinkedTo=" * (Example value: Node_3)*
STEP2: Then Stop
STEP3: Go to the previous NodePosX= and copy the value * (Example value: 10)*
STEP4: Go to the previous NotePosY= and copy the value * (Example value: 100)*
STEP5: Then find the next "Node_3" on the document
STEP6: And replace inside the NodePosX=30 and NodePosY=300 for the copied values 10 and 100
STEP7: Then look for the next "LinkedTo=" * (Example value: Node_5)* and repeat the STEP2 to STEP5
This is how it looks like Before running the Python script:
Begin
Name="Node_1"
NodePosX=10
NodePosY=100
LinkedTo=Node_3
LinkedTo=Node_5
End Object
Begin
Name="Node_2"
NodePosX=20
NodePosY=200
End Object
Begin
Name="Node_3"
NodePosX=30
NodePosY=300
End Object
Begin
Name="Node_4"
NodePosX=40
NodePosY=400
End Object
Begin
Name="Node_5"
NodePosX=50
NodePosY=500
End Object
This is how it should look like AFTER running the Python script:
Begin
Name="Node_1"
NodePosX=10
NodePosY=100
LinkedTo=Node_3
LinkedTo=Node_5
End Object
Begin
Name="Node_2"
NodePosX=20
NodePosY=200
End Object
Begin
Name="Node_3"
NodePosX=10
NodePosY=100
End Object
Begin
Name="Node_4"
NodePosX=40
NodePosY=400
End Object
Begin
Name="Node_5"
NodePosX=10
NodePosY=100
End Object
Do you think am asking to much from Python to do?
Any better suggestions for the title to this problem?

I've created a treewidget with children which contain tables. I'd like to acces the contents of the QtableWidget but I cannot find how to do this?
The treewidget looks like:
I've generated the treewidget like:
software = QTreeWidgetItem(['Software'])
hardware = QTreeWidgetItem(['Hardware'])
beide = QTreeWidgetItem(['Beide'])
andere = QTreeWidgetItem(['Andere'])
i = 0
for key, value in sorted(data.items()):
if value['Subtype'] == 'Software':
sub = software
if value['Subtype'] == 'Hardware':
sub = hardware
if value['Subtype'] == 'Beide':
sub = beide
if value['Subtype'] == 'Andere':
sub = andere
l1 = QTreeWidgetItem(sub)
if value['Privacy'] == 'Voorzichtig':
l1.setBackgroundColor(0, QColor('orange'))
if value['Privacy'] == 'Vertrouwelijk':
l1.setBackgroundColor(0, QColor('red'))
l1.setTextColor(0, QColor('white'))
l1.setText(0, value['sDesc'])
self.treeMainDisplay.addTopLevelItem(l1)
l1_child = QTreeWidgetItem(l1)
self.item_table = QTableWidget()
self.item_table.verticalHeader().setVisible(False)
self.item_table.horizontalHeader().setVisible(False)
self.item_table.setColumnCount(5)
self.item_table.setRowCount(5)
c1_item = QTableWidgetItem("%s" % value['sDesc'].encode('utf-8'))
self.item_table.setItem(0, 0, c1_item)
c2_item = QTableWidgetItem("%s" % value['Type'].encode('utf-8'))
self.item_table.setItem(1,0, c2_item)
qt_child = self.treeMainDisplay.setItemWidget(l1_child, 0, self.item_table)
self.treeMainDisplay.addTopLevelItem(software)
self.treeMainDisplay.addTopLevelItem(hardware)
self.treeMainDisplay.addTopLevelItem(beide)
self.treeMainDisplay.addTopLevelItem(andere)
I'm iterating over the treewidgetitems but don't know how to access the table contents:
def testItems(self):
iterator = QTreeWidgetItemIterator(self.treeMainDisplay)
while iterator.value():
item = iterator.value()
if not item.text(0):
#Get Table Object?
# item.item(0,0).text()
else:
print item.text(0)
iterator += 1
It seems I can't get acces to the QTableWidget object, I only get the QTreeWidgetItem object.
All feedback is highly appreciated!
The item widgets must be access via the tree-widget using the itemWidget method:
def testItems(self):
iterator = QTreeWidgetItemIterator(self.treeMainDisplay)
while iterator.value():
item = iterator.value()
if not item.text(0):
# Get Table Object
table = self.treeMainDisplay.itemWidget(item, 0)
else:
print item.text(0)
iterator += 1
I am trying to read a file where the odd lines are department numbers, and even ones are sales totals. I need to be able to read a line and append it to a variable to be used later.
def main():
with open('P2data.txt') as x:
data = x.readlines()
dept = (data)[::2]
sales = (data)[1::2]
if dept == '1':
total = sales.next()
total.append(total1)
elif dept == '2':
total = sales.next()
total.append(total2)
else:
total = sales.next()
total.append(total3)
print('Dept 1:', total1)
print('Dept 2:', total2)
print('Dept 3:', total3)
main()
Your code is going in the wrong direction. You also are doing things like checking an entire data structure against what should be compared to one of that structure's elements, and mixing up the syntax for appending to a list. Simply loop over the data structures you create and add to a dictionary:
def main():
with open('P2data.txt') as x:
data = [line.strip() for line in x]
dept = data[::2]
sales = data[1::2]
totals = {'1':0, '2':0, '3':0}
for dep,sale in zip(dept, sales):
totals[dep] += float(sale)
for dep in sorted(totals):
print('Dept {}: {}'.format(dep, totals[dep]))
main()
