在文件A中,我从文件B导入了变量“ x”
我更改了文件A中的“ x”值
然后我覆盖文件B的“ x”声明。
现在,我需要在文件A中使用文件B中的新值“ x”。但是文件A并没有更新为文件B所获得的新值-它一直使用旧值(即不再存在)。如果我停止然后再次运行脚本,则文件A仅协调更改。
使用的真实姓名:
源文件A:
from blab import *
nm = 'nome'
while nm != 'proximo' :
from blab import * # here_point
import blab
from blab import vert
from blab import hor
nm = str(input('Cadastrar - nome : '))
pos = str(input(' Cadastrar - : %s . Ocupação : ' %(nm)))
grp = str(input(' Cadastrar - : %s . Grupo : ' %(nm)))
pos = pos.replace(" ", "_")
grp = grp.replace(" ", "_")
nm = nm.replace(" ","_")
if nm != 'proximo' :
if vert == -340:
new_vert = 350
new_hor = hor + 200
if vert!= -340:
new_vert= vert-30
new_hor = hor
txt_vert = new_vert - 15
txt_hor = new_hor + 20
with open("blab.py", "a") as fd:
fd.write("\nt%s = turtle.Turtle(shape='turtle')\nt%s.color('pink')\ntext%s = turtle\ntext(text%s, '%s', '20', 'green', %s, %s)\nt%s.goto(%s, %s)" %(nm,nm,nm,nm,nm,txt_hor,txt_vert,nm,new_hor,new_vert))
fd.write("\ndef t%s_handler(x, y):\n pnt = screen.textinput(' pontuação', '%s: ')" %(nm,nm))
fd.write("\n pnt = [int(x) for x in pnt.split()]\n if len(pnt) == 5 :\n with open('%s.py' %(mes), 'a') as fd:\n fd.write('%s.pontuacao(%i,%i,%i,%i,%i)' % (pnt[0],pnt[1],pnt[2],pnt[3],pnt[4]))\n" )
fd.write(" %s.color('blue')\n"%(nm))
fd.write("t%s.onclick(t%s_handler)\n"%(nm,nm))
print(vert,new_vert,hor,new_hor)
with open('blab.py', 'r') as file:
filedata = file.read()
filedata = filedata.replace('vert=%i' %(vert),'vert=%i' %(new_vert))
with open('blab.py', 'w') as file:
file.write(filedata)
file.close()
with open('blab.py', 'r') as file:
filedatas = file.read()
filedatas = filedatas.replace('hor=%.i'%(hor),'hor=%.i'%(new_hor))
with open('blab.py', 'w') as file:
file.write(filedatas)
file.close()
源文件B:
import turtle
screen = turtle.Screen()
width = 1200
height = 1500
turtle.screensize(width, height)
def text(t,text, size, color, pos1, pos2):
t.penup()
t.goto(pos1, pos2)
t.color(color)
t.begin_fill()
t.write(text, font=('Arial', size, 'normal'))
t.end_fill()
vert=350
hor=-600
我试图在第7行重新导入变量,但这没有用。
注意:要运行一次脚本,只需在提示符下输入3个随机名称

这是您的示例的简化版本,它使用reload
-可以满足您的目的:
from importlib import reload
import blab
nm = 'nome'
while nm != 'proximo':
nm = str(input('Cadastrar - nome: '))
if nm != 'proximo':
new_vert = blab.vert - 100
new_hor = blab.hor + 100
print(blab.vert, new_vert, blab.hor, new_hor)
with open('blab.py') as file:
filedata = file.read()
filedata = filedata.replace('vert=%i' % blab.vert, 'vert=%i' % new_vert)
with open('blab.py', 'w') as file:
file.write(filedata)
with open('blab.py') as file:
filedatas = file.read()
filedatas = filedatas.replace('hor=%i' % blab.hor, 'hor=%i' % new_hor)
with open('blab.py', 'w') as file:
file.write(filedatas)
reload(blab)
输出

vert=350
hor=-600
