如何获取php执行python文件

Question

我正试图让php执行python程序，但它不想执行它。 python代码的重点是从文本文件中获取6位代码，从数据库中获取数据并对其进行操作，然后将该数据保存到.txt文件中。 通过IDLE运行它时，它工作得很好，但是php代码不会执行它。 这是怎么了

的PHP代码：

<?php
    $myfile = fopen("uniprocode.txt", "w+");
    $txt = $_POST['code'];
    fwrite($myfile, $txt);
    fclose($myfile);

    $result = exec('C:\ProgramData\Anaconda3\python.exe comp.py');
    $r = json_decode($result);
    foreach($r as $row){
        echo $row ."<br>";
    }
?>

python代码：

import re
from Bio import ExPASy
from Bio import SwissProt
from pathlib import Path
import os
import json

#uniprot ascension code regex from the uniprot site:
uniprotregex = '[OPQ][0-9][A-Z0-9]{3}[0-9]|[A-NR-Z][0-9]([A-Z][A-Z0-9]{2}[0-9]){1,2}'
#this string is {P}-{PKRHW}-[VLSWFNQ]-[ILTYWFN]-[FIY]-{PKRH}
#which i believe is a string that goes:
#"not P, not any of PKRHW, only VLSWFN or Q, only ILTYWF or N, only FI or Y, not any of PKRH"
protregex = '[^P][^P^K^R^H^W][VLSWFNQ][ILTYWFN][FIY][^P^K^R^H]'

g = open('uniprocode.txt')
y = g.readlines()
o = str(y)
t = o.strip("\'[]\'")
print(str(t))

def gogogo():
    try:
        hand = ExPASy.get_sprot_raw(str(t))
    except:
        f = open("sequencefinder.txt", "w+")
        f.write("Error: This is not a uniprot code.")
    else:
        data = SwissProt.read(hand)
        seq = data.sequence
        match = re.findall(protregex, seq)
        f = open("sequencefinder.txt", "w+)
        f.write("Protein\tStart position\tEnd position\tSequence\n")
        for m in re.finditer(protregex, seq):
            f.write(t + "\t" + str(m.start() + 1) + "\t\t" + str(m.end() + 1) + "\t\t" + str(m.group(0) + "\n"))
        f.close()
    r = open("sequencefinder.txt")
    return json.dumps(r)

if __name__ == "__main":
    print gogogo()
