dictionary output to text file (beginner)

[Pedroski55]

You could do that like this. First I need a dictionary containing some data:

# open any old text file
mytext = '/home/pedro/summer2023/breakingnewsenglish/UK_rationing.txt'
with open(mytext) as t:
    data = t.readlines()
print('data list is', len(data), 'long')
# make a dictionary
# all the keys are integers in this case, all the values are lines of text
mydict = {i:data[i] for i in range(len(data))}
# show the content of mydict
for item in mydict.items():
    print(item)

Now get some data from the dictionary and put it in a list

# an empty list to take the dictionary items you want to save in a text file
mylist = []
# just get the first 9 lines
for i in range(10):
    mylist.append(mydict[i])
# show the things to be saved to text
for m in mylist:
    print(m)

Now make the list into a string and write the string to the text file

# join the list to a string
# it is better to make a list than to create strings
# strings take up much more memory because they persist, so I have been told
mystring = ''.join(mylist)
# write the string to a text file
dict2text = '/home/pedro/summer2023/breakingnewsenglish/UK_rationing_part.txt'
with open(dict2text, 'w') as out:
    out.write(mystring)
    print('Some text from a dictionary saved as', dict2text)

3 steps to heaven! have fun learning!
