I'm trying to search through all the file in all sub-directories of my root directory to output lines that contain "key_phrases" that the user input. My current code can find and output lines for most files in my sub directories, but I cannot seem to find lines in certain files of the folder, almost as if they are invisible to the search. Below is my code for the python function and Tkinter GUI for the user to input the directory and key phrases. The Tkinter GUI is just for reference, I believe the problem is in the for loop of my Python function.
My Python Function
import os
def searchandOutput(rootdir, keyPhrases):
path = rootdir # Enter the root directory you want to search from
key_phrases = [keyPhrases] # Enter here the key phrases in the lines you hope to find
key_phrases = [i.replace('\n','') for i in key_phrases] #In case an "\n" is added to the end of the string when the parameter is passed to the function
# This for loop allows all sub directories and files to be searched
for (path, subdirs, files) in os.walk(path):
files = [f for f in os.listdir(path) if f.endswith('.txt') or f.endswith('.log')] # Specify here the format of files you hope to search from (ex: ".txt" or ".log")
#files = [f for f in files if f.endswith('.txt') or f.endswith('.log')]
files.sort() # file is sorted list
files = [os.path.join(path, name) for name in files] # Joins the path and the name, so the files can be opened and scanned by the open() function
# The following for loop searches all files with the selected format
for filename in files:
# Opens the individual files and to read their lines
with open(filename) as f:
f = f.readlines()
# The following loop scans for the key phrases entered by the user in every line of the files searched, and stores the lines that match into the "important" array
for line in f:
for phrase in key_phrases:
if phrase in line:
print(line)
break
print("The end of the directory has been reached, if no lines are printed then that means the key phrase does not exist in the root directory you entered.")

I have a python code :
import gdal
import numpy
from skimage.filters import threshold_otsu
ds = gdal.Open('A:\\algo\\f2.tif')
In this code, line 4 gives the location/path of "input file" and line 10 gives the location of "output file".
I want to create a user interface to give this location in the user interface itself and run the code from user interface itself.
I have tried making a user interface using "tkinter" module :
from tkinter import *
from tkinter import filedialog
def input():
file1 = filedialog.askopenfile()
label = Label(text=file1).pack()
def input2():
file2 = filedialog.asksaveasfile(mode="w", defaultextension=".tif")
label = Label(text=file2).pack()
w = Tk()
w.geometry("500x500")
w.title("FLOOD_MAPPER")
h = Label(text = "S1A FLOOD MAPPER", bg = "yellow", fg = "black", height = "3", width = "500")
h.pack()
i1 = Label(text = "Input*")
i1.place(x=10, y=70)
i1b = Button(w, text = "Select File", command =input)
i1b.place(x=250, y=70)
i2 = Label(text = "Intermediate Product*")
i2.place(x=10, y=140)
i2b = Button(w, text = "Save as", command =input2)
i2b.place(x=250, y=140)
button = Button(w, text="Generate Map", bg = "red", fg = "black", height = "2", width="30")
button.place(x=150, y=400)
w.mainloop()
But I didn't understand how to link these two codes.
The moment I click on button "generate map" in the user interface I want the location/path of Input and output given in the user interface box to move to their respective places in the 1st code and then run the same code aumoatically.
Kindly, help me to achieve my requirement.
It can look like this. I removed keep only important elements in tkinter.
I put code in your_code and it can get filenames as paramaters. So this code looks similar as before.
I create function gen_map which get run your_code with filenames which are assigned to global variables input_filename, `output_filename.
I assing gen_map to button Button( command=gen_map) so it will run it when you press button.
Other buttons open dialog to get file names and assign to global variables input_filename, output_filename.
from tkinter import *
from tkinter import filedialog
import gdal
import numpy
from skimage.filters import threshold_otsu
def your_code(input_file, output_file):
#ds = gdal.Open('A:\\algo\\f2.tif')
ds = gdal.Open(input_file)
band = ds.GetRasterBand(1)
arr = band.ReadAsArray()
thresh = threshold_otsu(arr,16)
binary = arr > thresh
driver = gdal.GetDriverByName("GTiff")
#outdata = driver.Create("A:\\algo\\test11.tif", 14823, 9985, 1, gdal.GDT_UInt16)
outdata = driver.Create(output_file, 14823, 9985, 1, gdal.GDT_UInt16)
outdata.SetGeoTransform(ds.GetGeoTransform())
outdata.SetProjection(ds.GetProjection())
outdata.GetRasterBand(1).WriteArray(binary)
outdata.GetRasterBand(1).SetNoDataValue(10000)
outdata.FlushCache() ##saves to disk!!
#outdata = None
#band = None
#ds = None
def get_input_filename():
global input_filename
# `askopenfilename` instead of `askopenfile` to get filename instead of object file
input_filename = filedialog.askopenfilename()
input_label['text'] = input_filename
def get_output_filename():
global output_filename
# `asksaveasfilename` instead of `asksaveasfile` to get filename instead of object file
output_filename = filedialog.asksaveasfilename(defaultextension=".tif")
output_label['text'] = output_filename
def gen_map():
#global input_filename
#global output_filename
print('input:', input_filename)
print('output:', output_filename)
your_code(input_filename, output_filename)
#---------------------------------------------
# global variables with default values at start
input_filename = 'A:\\algo\\f2.tif'
output_filename = "A:\\algo\\test11.tif"
root = Tk()
#input_label = Label(root, text=input_filename)
input_label = Label(root, text="Input*")
input_label.pack()
input_button = Button(root, text="Select File", command=get_input_filename)
input_button.pack()
#output_label = Label(root, text=output_filename)
output_label = Label(root, text="Intermediate Product*")
output_label.pack()
output_button = Button(root, text="Save as", command=get_output_filename)

Please advise on how to retrieve a file's full path into a variable after i pick one using tkinter
The whole idea of my GUI is to:
1. Have few buttions
2. Have address bar with file's full address
Once user clicks the button and picks the file >> file's path is displayed in the address bar as well as stored in a separate variable for future usage later in code
I've done some testing, but when checking for retrieved value - I get None.
def file_picker():
"""Pick enova .xlsx file"""
path = filedialog.askopenfilename(filetypes=(('Excel Documents', '*.xlsx'), ('All Files', '*.*')))
return path
file_button = tkinter.Button(root, text='Users File', width=20, height=3,
bg='white', command=custom_functions.file_picker).place(x=30, y=50)
Apart form that I found another code snippet, but this simply captures line onto the GUI interface, not saving file path in any variable though:
def browsefunc():
filename = filedialog.askopenfilename()
pathlabel.config(text=filename)
print(pathlabel)
browsebutton = tkinter.Button(root, text="Browse", command=browsefunc).pack()
pathlabel = tkinter.Label(root).pack()
Expected result: https://imgur.com/a/NbiOPzG - unfortunatelly I cannot post images yet so uploaded one onto imgur
To capture the full path of a file using Tkinter you can do the following. The output of your full file path will be displayed in the "Entry" field / your address bar as per your requirement in your original post.

I am trying to build a GUI that takes the root directory and key phrases as inputs from the user, and output all the lines in that directory that contains the key phrases the user enters. My python function works by itself when I enter in parameters manually, but when I try to bind it to my TKinter layout, and pass in variables by using the get function from the user's input, I keep getting "None" as a result. I am relatively new to Python, thank you so much for your help!

i have written a program that creates numberd directories inside other directories it works fine except one little issue that is the most important. the entry that is used in the while loop can't convert into a base 10 integer. i have tried several ways and found nothing that would help me..

The problem is when you call
num_entry_in = num_entry.get()
Currently you call it right away, as soon as num_entry is created, so of course the field is empty and returns "" (an empty string), and int("") gives ValueError.
You need to put it inside flood() so that it runs when the button is pressed, after the user has entered something. You also need to check the result to make sure it actually is a number, ie
try:
num_entry_in = int(num_entry.get())
except ValueError:
# not a an int!
# pop up a warning to let the user know what went wrong
My problem is how to use the file I will select with askopenfilename() later on, for example to put it the canvas ?
What should I put instead of the "?" at "Im = ?" ?
Thank you !
Sorry I am very much a beginner

Use this code to store a file as a variable:
path = tkFileDialog.askdirectory()
os.chdir(path)
f = open(file_name, mode)
mode can be:
'r' - if you want to read data from the file.
'w' - if you want to write data to the file.
You can read the data of the file using the command: file.read().
And write data using the command: file.write(data)(The mode should be accordingly).
Read further in here.
Hopefully this will help you,Yahli.
