I have a text file as follows:
myfile.txt
[items]
colors = red, purple, orange, blue
[eat]
food = burgers, pizza, hotdogs
[furry]
animals = birds, dogs, cats
I have a dictionary:
my_dict = {'colors':'green, black','animals':'donkey, tigers'}
I want to open the file myfile.txt and search for the keys inside the file and replace the lines with the values of my_dict so that myfile.txt should look like:
myfile.txt
[items]
colors = green, black
[eat]
food = burgers, pizza, hotdogs
[furry]
animals = donkey, tigers
I've tried doing something like:
# Get the file contents like you were already doing
with open('myfile.txt', 'r') as file:
filedata = file.read()
# Now split the rows on newline
lines = filedata.split('\n')
# Create an empty dictionary
pairs = {}
# Process each line of the file's contents
for line in lines:
# If it doesn't have an '=', skip the line
if "=" not in line: continue
key, value = line.split("=")
# fill the dictionary with the keys and values in the file
pairs[key.strip()] = value.strip()
my_dict = {'colors': 'green, black', 'animals': 'donkey, tigers'}
# replace the previous files values with any new values from the new dictionary
for k, v in my_dict.items():
pairs[k] = v
# format the dictionary back into a line of text "colors = blue, black, etc."
new_lines = [f'{k} = {v}' for k, v in pairs.items()]
with open('myfile.txt', 'w') as file:
# join the new lines for the file with a newline character
file.write('\n'.join(new_lines))
The problem is that I get an output like:
myfile.txt
colors = red, purple, orange, blue
food = burgers, pizza, hotdogs
animals = birds, dogs, cats
Where all the text in the brackets has been discarded. I need to keep the headings too [items], [eat], etc..
