Python报错TypeError: 'str' object is not callable，在线方案无效求助

Hey there! I’ve run into this exact error before, so let’s break it down and fix it quickly.

What’s causing this error? #

The error TypeError: 'str' object is not callable on line 7 means you’ve accidentally overwritten Python’s built-in input() function with a string variable somewhere.

For example, if you ran something like input = "New York" earlier in your session (either in the same script or in an interactive shell/Jupyter notebook), you turned the input name into a string. When your code tries to call input('Enter location: '), it’s trying to run that string like a function—which doesn’t work!

How to fix it #

• Check for variable name conflicts: Scan through your code (and any previous code cells if you’re using a notebook) to see if you’ve assigned a value to a variable named input. Rename that variable to something else (like user_input or location_input) to avoid clashing with the built-in function.
• Reset your Python environment: If you’re working in an interactive shell or Jupyter notebook, restart the kernel/shell. This will restore the original built-in input() function, since the overwrite only exists in your current session.
• Temporary workaround (not ideal, but works): If you can’t restart right now, you can explicitly call the built-in version like this:

  input_str = __builtins__.input('Enter location: ')
  

  But again, renaming conflicting variables is the cleaner long-term fix.

Verifying your code #

Looking at the full code you shared, there’s no direct overwrite of input in the script itself. That means the issue is almost certainly from a previous line of code you ran in the same session that used input as a variable name. Restarting your environment should get things working again.

Here’s your original code with a note to avoid variable name clashes:

import urllib.request, urllib.parse, urllib.error
import xml.etree.ElementTree as ET
serviceurl = 'http://maps.googleapis.com/maps/api/geocode/xml?'
while True:
    # Make sure you haven't used 'input' as a variable name elsewhere!
    input_str = input('Enter location: ')
    if len(input_str) < 1: break
    url = serviceurl + urllib.parse.urlencode({'address': input_str})
    print('Retrieving', url)
    uh = urllib.request.urlopen(url)
    data = uh.read()
    print('Retrieved', len(data), 'characters')
    print(data.decode())
    tree = ET.fromstring(data)
    results = tree.findall('result')
    lat = results[0].find('geometry').find('location').find('lat').text
    lng = results[0].find('geometry').find('location').find('lng').text
    location = results[0].find('formatted_address').text
    print('lat', lat, 'lng', lng)
    print(location)

Give these steps a try—your code should run as expected once the input function is no longer overwritten!
