1、list转换成字符串 命令:list() 例子: 2、字符串转换成list 命令:"".join(list) 其中,引号中是字符之间的分割符,如“,”,“;”,“\t”等等 例子:
接下来,我们需要调用转换函数convert_number_to_text()将数字转换为相应的文本。可以使用如下代码实现: text=convert_number_to_text(num) 1. 这段代码将调用自定义的convert_number_to_text()函数,将转换后的文本赋值给变量text。 最后,我们可以使用print()函数将转换后的文本输出。可以使用如下代码实现: print(t...
Assign the decoded string to a variable. Use the decoded string in your Python code as needed. You can convert that string back to bytes with UTF-16 encoding using theencode()method: # Define a stringstring='sparksbyexamples'# Encode the string to bytes in UTF-16byte_string=string.encode...
profit = float(browser.find_element_by_xpath('/html/body/div[3]/section[16]/section[2]/section[2]/section[2]/div/div[1]/table/tbody/tr/td[15]/span').text) ValueError: could not convert string to float: '' 前5行是无用的。在第6行,我打印了我试图获得的浮点()的东西。如您所见,它...

But first, a very important note here. The string that we manipulate using the Python built-in >methods does NOT change the value of the string itself. 例子: text = "Please convert me to all uppercase" print(text.upper()) # output: PLEASE CONVERT ME TO ALL UPPERCASE ...
