我正在尝试使用 Python 和 Selenium 在文本框中输入一个长字符串（大约 4000 个字符）。

输入完整的字符串后，文本框中的整个内容就会消失，并出现以下错误：

内部停止迭代：假

c:\users\echo\anaconda3\lib\site-packages\ipython\core\interactiveshell.py(3058)run_cell_async() -> interactivity=interactivity, compiler=compiler, result=result)

在调试模式下，我使用 send_keys("aapl") 进行了测试，它工作正常，但不适用于长字符串。该循环也可以正常工作，并提供一个包含大约 800 个用逗号分隔的符号的字符串。

我的代码：

# Get symbols from Excel

filename = "file path"
wb1 = xl.load_workbook(filename)
ws1 = wb1.worksheets[8]
mr = ws1.max_row
symbols = ""
for i in range(2, mr + 1):
        c = ws1.cell(row = i, column = 1)
        if isinstance(c.value, str):
            symbols += f",{c.value}"
        else:
            print(c)

# Input symbols to Watchlist

WebDriverWait(driver, 30).until(EC.visibility_of_element_located((By.XPATH, '//input[@data-ng-model="userEnteredSymbols"]'))).send_keys(symbols)

# The code for the website:

    <input type="text" autocomplete="off" autocorrect="off" autocapitalize="off" placeholder="Add a symbol..." class="sec-search-box bc-form__add-symbol-input ng-pristine ng-invalid ng-invalid-required ng-touched placeholder" data-ng-model="userEnteredSymbols" data-barchart-clear-input="" required="">```

So the issue is resolved. I used a generator and looped through it, not sure how, but it works now.

def gen_function():
l = symbols
for s in l:
    yield s
gen_obj = gen_function()

# Input symbols to Watchlist
for s in gen_obj:
    WebDriverWait(driver, 30).until(EC.visibility_of_element_located((By.XPATH, '//input[@data-ng-model="userEnteredSymbols"]'))).send_keys(s)
