I'm trying to make Spotify automatic song listener with selenium, but I'm getting an error while pressing the play button, please help.

The error I got:

CodePudding user response：

This error message...

SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//[@id="main"]/div/div[2]/div[3]/div[1]/div[2]/div[2]/div/div/div[2]/main/section/div[3]/div/div[1]/button' is not a valid XPath expression

...implies that the xpath expression you have constructed isn't a valid expression.

While constructing an xpath, the expression need to start with a tag_name e.g. <div>, <table> etc or * and always preceded by a double frontslash i.e. //

Solution

Effectively, your line of code will be:

driver.find_element(by=By.XPATH, value='//*[@id="main"]/div/div[2]/div[3]/div[1]/div[2]/div[2]/div/div/div[2]/main/section/div[3]/div/div[1]/button').click()
