如何避免此错误“SyntaxError：解析时意外 EOF”

Question

while True:
    try:
        result = login(browser, url)
        if not result != 0:
            login(browser, url)
            while True:
                try:
                    time.sleep(1)
                    browser.find_element_by_class_name("submit").click()
                except:
                    browser.find_element_by_xpath("//a[contains(.,'Restart Battle')]").click()

It shows error on this line:

browser.find_element_by_xpath("//a[contains(.,'Restart Battle')]").click()

I tried removing parentheses and spaces and other stuff, but it isn't going off.

Any idea what I should do?

Answer 1

When using try, you need an except. For example, the following code prints error :

try:
    x=1/0
except:
    print("error")

But this throws an SyntaxError: unexpected EOF while parsing :

try:
    x=1/0
# except:
#   print("error")

So, you need an exception at the end of the try statement here:

while True:
    try:
        result = login(browser, url)
        if not result != 0:
        ...
    except:
        ...

This error means that in your script something begins , but the EOF (End of File — the file is your script) occurred before it ends.

(Similar as the unexpected “The End” in a watched crime thriller without revealing a perpetrator.)

It means that you started something (eg writing " as a start of the string literal), but you never ended it (no closing " ).

The typical cases are unbalanced quotes, apostrophes, parentheses, and so on.

In your case it is the first try: without the expected except: just in the 2 ^nd line of your script.
