Use paiza's skill check to study python. Among them, I thought about a configuration to reproduce the standard input locally and test it, so make a note. Please point out any typos, more efficient ways, etc.

$ python ./answer.py < ./input.txt

Preparation

Installation of python3. Introduction of pyperclip used for copying the clipboard Reference: Clipboard operation with python

Directory structure

.
├── answer.py #File for improving the production environment
├── conv.py #File for local conversion
├── input.txt #Input example file
└── proto.py #Main program description file

File contents

answer.py and input.py are empty at first, so the other two.

proto.py --For writing the main program

`proto.py`


#Creating a local execution environment
#Open file

inp =  open("input.txt", mode="r")

#----Program from here----



#----Program so far----

#File close
inp.close()

conv.py --For local specific description conversion

`conv.py`


#Regular expression import
import re
#Module import copy to clipboard
import pyperclip

#Read file for conversion
with open("proto.py", mode="r") as prot, open("answer.py", mode="w") as answ:
    #Loading the local environment
    for line in prot:
        #Replace keywords dedicated to local development environment with standard input
        tmp = line.replace('inp =  open("input.txt", mode="r")','')\
                 .replace('inp.readline()','input()')\
                 .replace('inp.close()','')
        #Delete comment
        tmp = re.sub(r'#.*','',tmp)
        #Export other than blank lines
        if tmp != '\n':
            answ.write(tmp)

#Load the answer for clipboard copy
with open("answer.py", mode="r") as answ:
    pyperclip.copy(answ.read())

procedure

1. Add input example, get standard input

First, copy and paste the standard input input example into input.txt as it is. Also, program from the comment of proto.py-Program from here. For standard input, get line by line with the following code.

`proto.py`


#For 1 row 1 data
date = inp.readline().rstrip() #rstrip removes rightmost blanks and line breaks

#For multiple data per line
date = inp.readline().rstrip().split(' ') #List by blank delimiter by split

2. Programming, testing

Programming as usual. Type the following command in the terminal each time and search while checking the result.

`python`


$ python proto.py

3. Convert to production environment, copy

After completion, delete the locally specific program and convert it to standard input with conv.py. Also copy to clipboard. All you have to do is paste it into the submission form.
