Python problem: opening and closing a file returns a syntax error

Hi guys I've fonund this useful python script that allows me to get some weather data from a site. I'm going to create a file and the dataset indide.

Something is not working. It returns this error. 

File "<stdin>", line 42
     f.close()
     ^
SyntaxError: invalid syntax

What's wrong? In this line I'm only closing the file! Could anyone help me please?

This is the python code. 

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()

I had the same problem today 2020(October), and I just checked the code above the close() function. I found I hadn't closed a bracket earlier. So the error is in the code above the function and not the actual line specified.

I had a similar Error showing syntax error in 3.8 just now. And it turns out, my syntax error was a missing closing parenthesis in code above the highlighted line. So, line 42 is not what Question Putter should be looking at. Perhaps, there is actually a syntax error somewhere above in the code.

Delete lines in your code until the syntax error goes away. Then you'll be able to narrow the problem.

The line with the f.close() isn't line 42, so are you sure this is the code that gives the error?

Also, Python seems to process a program received on stdin, is this your intention?

Looks like you have a whitespace problem in there. Check the whitespace of the file - see where spaces and tabs are. If there are both tabs and spaces in the file, convert them all to spaces.

f.close should be at the same indentation level as f = open('wunder-data.txt', 'w')
