如何链接独立的python代码以在烧瓶中使用。

例如

import sys

# By design, the patterns come in one per line piped in from STDIN

for line in sys.stdin.readlines():
line = line.strip()
# 1) Split the pattern into clauses. 
# 2) Translate each clause into regex syntax
# 3) reassemble the full regex pattern
clauses = line.split("-")
regex_clause_array = []
for clause in clauses:
    # re_clause: the incremental build-up of the clause into regex syntax
    re_clause=None
    # Convert the prosite negation into a regex inverted character class
    if clause.startswith("{"):
        neg_pieces = clause.split("}")
        # neg_pieces[0][1:] is the character set for the negation
        # neg_pieces[1] is the optional quantification
        re_clause = "[^%s]%s" % (neg_pieces[0][1:], neg_pieces[1])
    else:
        re_clause = clause
    # change the quantification parenthesis into regex curly-braces
    re_clause = re_clause.replace(")","}")
    re_clause = re_clause.replace("(","{")
    # change wildcards from 'x' to '.'
    re_clause = re_clause.replace("x",".")
    # save the regex-syntax clause to the regex clause array
    regex_clause_array.append(re_clause)
# add the leading and trailing slashes and concatenate all regex clauses
# together to form the full regex pattern
print ("/%s/" % ("".join(regex_clause_array)))

上面的代码单独工作，它需要一个序列，例如Px（2）-GESG（2） - [AS]并转换为python正则表达式P. {2} GESG {2} [AS]。

我无法弄清楚的是，我正在尝试使用flask将其链接到webtool。我现在拥有的是一个简单的网页，它有一个文本框和一个提交按钮，但无法将上述代码链接到路由应用程序。

将代码放在不同的python文件中并命名。现在，您可以将python文件用作模块。将代码放在一个函数中。你可以在flask中导入python文件。

 from filename import function

您可以在

等视图中使用它

@app.route('/link' , methods = ['POST'])
def view_function():
     call = function()

现在在提交按钮中，您可以执行以下操作：

<form action="/link" method = 'post'>
    <input type="submit" value="submit" />
</form>

将python代码链接到FLASK
