Question

我正在尝试在Python中以不同的方向显示网格，还有另一种方法可以垂直，透视等方式执行此操作吗？我有时也由于某种原因说“在分配之前引用了局部变量'错误'”，但是在另一个Flask程序中，这并不是我遇到的问题。当前，网格水平显示颜色。

编辑-所以我设法解决了分配错误之前引用的问题，事实证明这是一个缩进问题。我试图更改网格上的颜色，将值与带有颜色的变量代入，这无济于事。我还在POST请求方法下添加了if请求方法=='GET'，并指出如果发出了get请求，则中止。

关于如何在POST请求上重新安排网格，我还是一无所知。我添加了request.form ['type.h-stripes']，当我按照文档中的示例进行操作时，该响应返回错误响应，并且未定义随机播放。

from flask import Flask, render_template, request
import time
import random

app = Flask(__name__) # creates applications instance
app.config.from_object(__name__) # loads configuration from this file, flaskr.py



@app.route('/', methods=['GET', 'POST'])
def homepage():
#print ("time.time(): %f " % time.time())
#print (time.localtime(time.time()))
curent_time = (time.asctime(time.localtime(time.time())))

if request.method == 'POST':
    error = None
    type = request.form['type'] # takes the name value in the html

# Colour 4 being the last colour specified in the array, cahnging displaycolur1 (as an example) to #000000 will force the colour to display as a black colour as it is in hex value
    randomcolourr1 = lambda: random.randint(0,255)
    displaycolu1 = ('#%02X%02X%02X' % (randomcolourr1(),randomcolourr1(),randomcolourr1()))

    randomcolourr2 = lambda: random.randint(0,255)
    displaycolu2 = ('#%02X%02X%02X' % (randomcolourr2(),randomcolourr2(),randomcolourr2()))

    randomcolourr3 = lambda: random.randint(0,255)
    displaycolu3 = ('#%02X%02X%02X' % (randomcolourr3(),randomcolourr3(),randomcolourr3()))

    randomcolourr4 = lambda: random.randint(0,255)
    displaycolu4 = ('#%02X%02X%02X' % (randomcolourr4(),randomcolourr4(),randomcolourr4()))

    randomcolourr5 = lambda: random.randint(0,255)
    displaycolu5 = ('#%02X%02X%02X' % (randomcolourr5(),randomcolourr5(),randomcolourr5()))

*EDIT*    if request.form['type.h-stripes']: # if request.form contains the type name and h-stripes value being selected
    tablehori = ('color0, color1, color2, color3, color4'.split()) # takes colour values from the table td elements
    shuffle(tablehori) # not defined
    print (tablehori) # prints to console

return render_template('index-example.html', error=error, curent_time=curent_time, displaycolu1=displaycolu1, displaycolu2=displaycolu2, displaycolu3=displaycolu3, displaycolu4=displaycolu4, displaycolu5=displaycolu5)

app.run(debug=True)
