Str object is not callable in Kivy

I'm using Kivy in python trying to make the button "Save" run the "Save_number" function but I keep getting a "TypeError: 'str' object is not callable"-error. Below is relevant code.
class DBScreen(Screen):
def save_number(self):
conn = sqlite3.connect('database.db')
c = conn.cursor()
name = self.ids.save_name.text
number = self.ids.save_number.text
name = str(name).replace("(","").replace(")","").replace(",","").replace("'","")
number = str(number).replace("(", "").replace(")", "").replace(",", "").replace("'", "")
number = int(number)
c.execute("INSERT INTO database VALUES (?,?)", (name, number))
c.execute("SELECT * FROM database WHERE name=:name", {'name': name})
conn.commit()
conn.close()
pass
def save_process(self):
self.save_name = self.ids.save_name.text
self.save_number = self.ids.save_number.text
if self.save_number == "" and self.save_name == "":
self.disable_save()
elif self.save_number != "" and self.save_name != "":
self.enable_save()
pass
def disable_save(self):
self.ids.save_button.disabled = True
def enable_save(self):
self.ids.save_button.disabled = False
def load_number(self):
global number_list
global initial_length
conn = sqlite3.connect('database.db')
c = conn.cursor()
name = self.ids.load_name.text
if self.ids.load_name.text == "":
self.disable_submit()
else:
self.enable_submit()
c.execute("SELECT * FROM database WHERE name=:name", {'name': name})
name, number = c.fetchone()
conn.commit()
conn.close()
number_list = []
for i in number:
number_list.append(int(i))
initial_length = len(number_list)
def load_process(self):
self.load_text = self.ids.load_name.text
print(self.load_text)
if self.load_text == "":
self.disable_load()
else:
self.enable_load()
def disable_load(self):
self.ids.load_button.disabled = True
def enable_load(self):
self.ids.load_button.disabled = False
Below is the relevant part of the Kivy file

You have a function and a TextInput with the same name number and both of them are in root (DBScreen), so the interpreter doesn't understand which name you call and calls a TextInput, not a function as you expected. To fix the problem give a TextInput another name

kivy - textinput from kv to py - import data

I'm trying to get the data from a simple textinput that is in my kv file and use the information in my python file.
but i keep getting the same error.
this error happens when i press a button and the function try to run looks like its trying to get the information from the text_location widget
thank you in advance.
class ScatterTextWidget(BoxLayout):
def initialize_request(self):
''' Initial analysis and control flow of the class '''
location = self.ids.input_location
date = S.ids.input_date
time_raw = ScatterTextWidget.ids.input_time
print(f'{location} - {date} - {time_raw}')
class HistoricalApp(App):

return ScatterTextWidget()

i reduce it because is kind of long

thank you in advance
best,

First, you need to remove both of the id:input1 lines and the id:input2 line. Then change your initialize_request method to:
def initialize_request(self):
''' Initial analysis and control flow of the class '''
location = self.ids.text_location.text
date = self.ids.input_date.text
time_raw = self.ids.input_time.text
print(f'{location} - {date} - {time_raw}')
Note that self.ids.text_location is a reference to the TextInput widget, so you have to add .text to get its text. Same for the other TextInput widgets.

can i use for statement in .kv file?

GridLayout:
cols:
rows: root.numberoflist
for i in range(root.businfolist):
Label:
font_name: 'C:/Windows/Fonts/HYWULM'
text_size: cm(2), cm(2)
pos: self.pos
id: my_custom_label
text: root.businfolist[0]
color: [255,255,255,1]
.kv file
i want use FOR STATEMENT to .kv file and i saw the
https://kivy.org/docs/api-kivy.lang.html?highlight=statement
this page, but i don't understand.
i think indentation seems to be wrong.
what is wrong with these code?
traceback is here thank you for read my question.

Add import statement, #:import Label kivy.uix.label.Label
Use on_parent event to execute the for loop in kv file
Valid expressions
There are two places that accept python statements in a kv file:
after a property, which assigns to the property the result of the expression (such as the text of a button as shown above) and
after a on_property, which executes the statement when the property is updated (such as on_state).

Kivy importing Python variables into inline KV

I've been banging my head off this particular wall for days now. None of the relevant articles here have worked, so I really need to know where I'm going wrong. The relevant sections of code are:
def print_scb(myscb):
print(myscb)
scb_string = ''
scb_list = [ 'Combat' , 'Communication' , 'Manipulation' , 'Mental' , 'Perception', 'Physical' ]
for s in scb_list:
zz = str(myscb[s])
scb_string = scb_string + s + " " + zz + "% "
return scb_string
And the inline KV section is:
<CharacterSheet>:
BoxLayout:
orientation: 'vertical'
Label:
text:'Stats'
Label:
text: app.print_stats()
Label:
text:'Rolls'
Label:
text: app.print_rolls()
Label:
text:'SCM'
Label:
text: app.print_scm()
Label:
text:'SCB'
Label:
text: app.print_scb()
Button:
text:'Quit'
on_press: sys.exit()
Button:
text:'Back to Start'
on_press: root.manager.current = 'welcome'
""")
The program crashes with:
kivy.lang.BuilderException: Parser: File "<inline>", line 114:

The whole code has been posted to dpaste at BrpGui.py
The print_scb() functions returns a string.
Any ideas where I'm going wrong?
Colin

As you mentioned in the comments.
print_scb is not a global function. It is defined in the CharacterSheet(Screen): class.
When you defined the function you forgor self.
So instead of def print_scb(myscb): it shall be def print_scb(self, myscb):
Also in your kv file, dont use app.print_scb() but root.print_scb()
Since it belongs to that class.
But since your function wants a parameter, it will throw an error. So you need to call it with a parameter. like this root.print_scb(some_variable)
From the docs https://kivy.org/docs/guide/lang.html -
There are three keywords specific to Kv language:
app: always refers to the instance of your application.
root: refers to the base widget/template in the current rule
self: always refer to the current widget

Kivy - How to access kivy widget in python?

I want to edit a text in a TextInput in kivy but don't know how to, I've tried this code as Ive search in the net but still no luck.
class MainApp(Screen):
def __init__(self,**kwargs):
super(MainApp,self).__init__(**kwargs)
pass
class Forms(BoxLayout):
def __init__(self, **kwargs):
super(Main,self).__init__(**kwargs)
self.ids.txtSearch.text = "new text"
class Main(App):
def build(self):
return root_widget
if __name__ == "__main__":
Main().run()
------kivy-------
<Main>:
TextInput:
id: txtSearch
this is not my whole code but I think those are what matters in the issue
this is the error:

To change Widgets properties in kivy you need to 'link' the widget between .py and .kv file, first in .py file:
txt_Search = ObjectProperty()
then in .kv file, in your root widget:
txt_Search: txtSearch
then assign the id to a widget (as you already did):
<Main>:
TextInput:
id: txtSearch
text: ' '
then in your .py file, you can change attributes of the widget by doing this:
self.txt_Search.text = 'New Text'
or any other attribute:
self.txt_Search.height = '30dp'

Are you sure self.ids.txtSearch exists when you try to assign a text to it? You're calling super(Main,self) one line above so I guess txtSearch is never instantiated.
Btw, it's better to init widgets in *.kv files:
<Main>:
TextInput:
id: txtSearch
text: "new text"
