How to use string variable instead of literal string with double quotes inside a python function? [duplicate]

Question

I have a function in Python:

def clickButtonViaText():
    url = 'https://finance.yahoo.com/quote/AAPL/balance-sheet?p=AAPL'
    options = Options()
    options.add_argument('--headless')
    driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
    driver.get(url)
    WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//button[@aria-label="Total Assets"]'))).click()
    time.sleep(10)
    soup = BeautifulSoup(driver.page_source, 'html.parser')

I want to add an argument to my function that takes a string and I want to pass the string in //button[@aria-label="Total Assets"] as something like //button[@aria-label=str_variable] where str_variable is an argument passed with the function. Example: def clickButtonViaText(str_variable):

There are several ways of how to achieve this. Have a look at string formatting — ThiloOS

@ShadowRanger what do you mean? def clickButtonViaText(str_variable='"Total Assests"'): print(f'//button[@aria-label={str_variable}]') — It_is_Chris

I closed this as a duplicate, but now I'm realizing the quotes might make it more tricky. I'm not very familiar with this area myself so I'm not sure, but here's an existing question that might be more precise: Using a variable in xpath in Python Selenium. And if str_variable might contain quote characters itself, there's probably some library with a quote() or escape() method that could handle it, possibly xml.sax.saxutils.quoteattr(). — wjandrea

with f-string you can get this as

def clickButtonViaText(str_variable):
    ...
    WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, f'//button[@aria-label="{str_variable}"]'))).click()
    ...
