网上说是元素找不到对应的
代码如下:
import turtle
file=open("C:/Users/jyz_1/Desktop/新建文本文档.txt")
file=file.read()
lines=file.split("重庆")
i=0
lsy=[]
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
lsy.append(t)
#find the 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=int(month+day)
lsx.append(date_on_x)
#draw axis
def drawx():
turtle.pu()
turtle.goto(-50,-50)
turtle.pd()
turtle.fd(240)
def drawy():
turtle.pu()
turtle.goto(-50,-50)
turtle.seth(90)
turtle.pd()
turtle.fd(160)
#comment the axis
def comx():
turtle.pu()
turtle.goto(-50,-65)
turtle.seth(0)
for i in range(1,13):
turtle.write(i)
turtle.fd(20)
def comy():
turtle.pu()
turtle.goto(-75,-50)
turtle.seth(90)
for i in range(-30,51,10):
turtle.write(float(i))
turtle.fd(20)
#draw the rainbow
def rainbow():
#define the color
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")
#let's draw!
for x,t in lsx,lsy:
turtle.pu()
turtle.goto(x,t)
turtle.pd()
turtle.circle(10)
drawx()
drawy()
comx()
comy()
rainbow()
报错:
Traceback (most recent call last):
File "C:\Users\jyz_1\AppData\Local\Programs\Python\Python37-32\32rx.py", line 92, in <module>
rainbow(t)
File "C:\Users\jyz_1\AppData\Local\Programs\Python\Python37-32\32rx.py", line 83, in rainbow
for x,t in lsx,lsy:
ValueError: too many values to unpack (expected 2)
但是我用len发现lsx,lsy长度相同
也就是说,lsx,lsy中的元素一一对应
那这个报错是怎么回事?
