大家好,我喜欢这个有用的python脚本,它允许我从一个站点获取一些天气数据。 我要创建一个文件和数据集indide。
有东西坏了。它返回此错误。
File "<stdin>", line 42
f.close()
^
SyntaxError: invalid syntax
怎么了?在这一行,我只是关闭文件! 有人能帮我吗?
这是python代码。
import urllib2
from BeautifulSoup import BeautifulSoup
# Create/open a file called wunder.txt (which will be a comma-delimited file)
f = open('wunder-data.txt', 'w')
# Iterate through year, month, and day
for y in range(1980, 2007):
for m in range(1, 13):
for d in range(1, 32):
# Check if leap year
if y%400 == 0:
leap = True
elif y%100 == 0:
leap = False
elif y%4 == 0:
leap = True
else:
leap = False
# Check if already gone through month
if (m == 2 and leap and d > 29):
continue
elif (m == 2 and d > 28):
continue
elif (m in [4, 6, 9, 10] and d > 30):
continue
# Open wunderground.com url
url = "http://www.wunderground.com/history/airport/KBUF/"+str(y)+ "/" + str(m) + "/" + str(d) + "/DailyHistory.html"
page = urllib2.urlopen(url)
# Get temperature from page
soup = BeautifulSoup(page)
dayTemp = soup.body.nobr.b.string
# Format month for timestamp
if len(str(m)) < 2:
mStamp = '0' + str(m)
else:
mStamp = str(m)
# Format day for timestamp
if len(str(d)) < 2:
dStamp = '0' + str(d)
else:
dStamp = str(d)
# Build timestamp
timestamp = str(y) + mStamp + dStamp
# Write timestamp and temperature to file
f.write(timestamp + ',' + dayTemp + '\n')
# Done getting data! Close file.
f.close()
删除代码中的行,直到语法错误消失。这样你就能缩小问题的范围。
带有
f.close()
的行不是第42行,所以您确定这是导致错误的代码吗?另外,Python似乎处理在
stdin
上接收到的程序,这是您的意图吗?你好像有个空格问题。检查文件的空白-查看空格和制表符的位置。如果文件中同时有制表符和空格,请将它们全部转换为空格。
f.close
应与f = open('wunder-data.txt', 'w')
