Text file to be read (the real one contains more numbers), called number_info.txt
veinti tres
23
veinti dos
22
veinti uno
21
veinte
20
tres
3
dos
2
uno
1
This is the code (I need help with this)
import re
def auto_coding_text_to_number():
with open('number_info.txt', 'r') as f:
#lines 0, 3, 6, 9, 12, 15, 18, ...
coloquial_numbers = []
#lines 0+1, 3+1, 6+1, 9+1, 12+1, 15+1, 18+1, ...
symbolic_numbers = []
n = 0
with open('number_to_text.py', 'w') as f:
f.write('import re\n\ndef number_to_text_func(input_text):\n')
#write replacement lines based on regex
if(" " in coloquial_numbers[n]):
#for example write this line: " input_text = re.sub(r"veinti[\s|-|]*tres", "23", input_text)"
if not (" " in coloquial_numbers[n]):
#for example write this line: " input_text = re.sub("tres", "3", input_text)"
f.write(" return(input_text)\n input_text = str(input())\n
print(number_to_text_func(input_text))")
n = n + 1
auto_coding_text_to_number()
And this is the correct file, called number_to_text.py, that should be written by the other script
import re
def number_to_text_func(input_text):
input_text = re.sub(r"veinti[\s|-|]*tres", "23", input_text)
input_text = re.sub(r"veinti[\s|-|]*dos", "22", input_text)
input_text = re.sub(r"veinti[\s|-|]*uno", "21", input_text)
input_text = re.sub("tres", "3", input_text)
input_text = re.sub("dos", "2", input_text)
input_text = re.sub("uno", "1", input_text)
return(input_text)
input_text = str(input())
print(number_to_text_func(input_text))
EDIT:
The lines inside the .txt file are structured like this
"veinti tres" <---- line 0
"23" <---- line 1
"veinti dos" <---- line 2
"22" <---- line 3
"veinti uno" <---- line 4
"21" <---- line 5
"veinte" <---- line 6
"20" <---- line 7
"tres" <---- line 8
"3" <---- line 9
Then I suggested separating them into 2 groups and storing them in 2 lists
#lines 0, 3, 6, 9, 12, 15, 18, ...
coloquial_numbers = ["veinti tres", "veinti dos", "veinti uno", "veinte", "tres"]
#lines 0+1, 3+1, 6+1, 9+1, 12+1, 15+1, 18+1, ...
symbolic_numbers = ["23", "22", "21", "20". "3"]
body_template = """ input_text = re.sub(r"{}", "{}", input_text)\n"""
And then the body of the function should be structured like this
input_text = re.sub(coloquial_numbers[n].replace(' ', '[\s|-|]'), symbolic_numbers[n], input_text)
Getting something like this in the function body of the output file
def number_to_text(input_text):
input_text = re.sub(r"veinti[\s|-|]*tres", "23", input_text)
input_text = re.sub(r"veinti[\s|-|]*dos", "22", input_text)
input_text = re.sub(r"veinti[\s|-|]*uno", "21", input_text)
input_text = re.sub("tres", "3", input_text)
return(input_text)
I omitted the reading/write steps for sake of simplicity. No rule(s) to specify the body of the meta function is given so I did a guess.
import re
# body-component of the meta-code
body_template = """ input_text = re.sub(r"{}", "{}", input_text)\n"""
# read from file
with open('number_info.txt', 'r') as fd:
text = fd.read()
# update body
body = ''
for n_text, n in re.findall(r'\n*([a-z\s]+)\n(\d+)', text):
body += body_template.format(n_text.replace(' ', '[\s|-|]'), n)
# other components of the meta-code
header = """import re
def number_to_text_func(input_text):
"""
tail = """\n return(input_text)
input_text = str(input())
print(number_to_text_func(input_text))"""
# merge together texts to be saved to file
meta_code = header + body + tail
print(meta_code)
Output (content of number_to_text.py)
import re
def number_to_text_func(input_text):
input_text = re.sub(r"treinta[\s|-|]y[\s|-|]uno", "31", input_text) # <-
input_text = re.sub(r"veinti[\s|-|]tres", "23", input_text)
input_text = re.sub(r"veinti[\s|-|]dos", "22", input_text)
input_text = re.sub(r"veinti[\s|-|]uno", "21", input_text)
input_text = re.sub(r"veinte", "20", input_text)
input_text = re.sub(r"tres", "3", input_text)
input_text = re.sub(r"dos", "2", input_text)
input_text = re.sub(r"uno", "1", input_text)
return(input_text)
input_text = str(input())
print(number_to_text_func(input_text))
From the comments:
read file per line, no regex
with open('number_info.txt', 'r') as fd:
lines = fd.read().split('\n')
symbolic_numbers, coloquial_numbers = [], []
for i, line in enumerate(lines):
if i % 3 == 0:
coloquial_numbers.append(line)
elif i % 3 == 1:
symbolic_numbers.append(line)
or read file with slices
with open('number_info.txt', 'r') as fd:
lines = fd.read().split('\n')
coloquial_numbers = lines[::3]
symbolic_numbers = lines[1::3]
