# check that columns have data if len(data) == 0: continue 由于表中的第一行仅包含标题,因此我们可以跳过此结果,如上所示。它也不包含任何<td>元素,因此在搜索元素时,不会返回任何内容。然后,我们可以通过要求数据的长度为非零来检查是否只处理包含数据的结果。 然后我们可以开始处理数据并保存到变量中...
Write a Python program to check whether a list contains a sublist. Sample Solution: Python Code: # Define a function named 'is_Sublist' that checks if list 's' is a sublist of list 'l'defis_Sublist(l,s):sub_set=False# Initialize a flag 'sub_set' to indicate whether 's' is a ...
In this code, we define a custom function calledindex_existsthat checks if a given index is within the valid range of a specified list. The function takes two parameters: the list to be checked (my_list) and the index to be validated (index_to_check), and it returns a Boolean value ...
The index method can’t return a number because the substring isn’t there, so we get a value error instead: In order to avoid thisTraceback Error, we can use the keywordinto check if a substring is contained in a string. In the case of Loops, it was used for iteration, whereas in...

In this code block, we first define a listmy_listcontaining three strings: “apple”, “banana”, and “cherry”. Then, we use theinoperator to check if “banana” is present inmy_list. If it is, the code inside theifstatement is executed, printing “Found!” to the console. ...
