lsx,lsy在函数内定义：
def date():
lsx=[]
dates=file.split("\n")
for date in dates:
if "-" in date:
if date.replace("-","").isnumeric()==True:
p1=date.index('-')#the first -
p2=date.find('-',p1+1)#the second -
month=date[p1+1:p2]
day=date[p2+1:]
date_on_x=float(month+"."+day)
lsx.append(date_on_x-50)
def coloring():
lsy=[]
lines=file.split("重庆")
i=0
for line in lines:
#index the temprature
inn=line.index('\n')#The first \n
inc=line.index("C")#The first C
if i==0:
tu=int(line[line.find('\n',inn+1)+1:inc])#The second \n
if "～" in line:
tl=int(line[line.index('～')+1:line.rindex('C')])
else:
tl=tu
i=i+1
else:
fn=line.find('\n',inn+1)
tu=int(line[line.find('\n',fn+1)+1:inc])#The third \n
if "～" in line:
tl=int(line[line.index('～')+1:line.rindex('C')])
else:
tl=tu
t=(tl+tu)/2#daily average temprature
if t<8:
turtle.color("purple")
elif 8<=t<12:
turtle.color("lightblue")
elif 12<=t<22:
turtle.color("green")
elif 22<=t<28:
turtle.color("yellow")
elif 28<=t<30:
turtle.color("orange")
elif t>=30:
turtle.color("red")
lsy.append(t)
在另一个函数那里调用：
def rainbow():
global lsx,lsy
#let's draw!
for i in zip(lsx,lsy):
turtle.pu()
turtle.goto(i)
turtle.pd()
coloring()
turtle.circle(10)
报错为：
Traceback (most recent call last):
File "C:\Users\jyz_1\AppData\Local\Programs\Python\Python37-32\32rx.py", line 105, in <module>
rainbow()
File "C:\Users\jyz_1\AppData\Local\Programs\Python\Python37-32\32rx.py", line 93, in rainbow
for i in zip(lsx,lsy):
NameError: name 'lsx' is not defined
