Yes, there is a difference. The join() method will require you to explicitly convert the numbers to strings before joining, whereas the str() function will convert the entire list to a string with brackets and
my_list = string_to_list(string) print(my_list) # [[1, 2, 3], [4, 5, 6]] ▍14、 计算两数差值 计算出2个数字之间的差值。 def subtract(a, b): return a - b print((subtract(1, 3))) # -2 print((subtract(3, 1))) # 2 上面的这个方法,需要考虑数值的先后顺序。 def subtrac...
In this code snippet, you define a list of colors using string objects separated by commas and enclose them in square brackets.Similarly, tuples are also collections of arbitrary objects. To define a tuple, you’ll enclose a comma-separated sequence of objects in parentheses (()), as shown...
Lists are similar to arrays (dynamic arrays that allow us to store items of different data types) in other programming languages. Create a Python List We create a list by placing elements inside square brackets [], separated by commas. For example, # a list of three elements ages = [19...
We don't have a comma after the first item in our list, so Python is concatenating that string literal with the one just after it:task_list = [ "Practice Python" "Buy groceries", "Do dishes", "Do laundry", ] This is one of the reasons that I prefer to use trailing commas after...
Python. You can use some of the approaches such asreplace(),forloop,re.sub(),translate()&maketrans()and list comprehension &join()functions to remove the commas from the string. In this article, I will explain how to remove commas from a string by using all these functions with examples...

Using a dictionary, you can store and look up things by name, which is often a useful alternative to a list. Python programs can translate JSON text into Python data structures. Compare python with other languages: Shell: If you use a terminal or terminal window, the program that reads ...
3. Convert the Tuple to a List Using * unpacking Method You can use unpack a tuple and assign its elements to a list by enclosing the tuple in square brackets[]and separating the elements withcommas. For example, you are using the*operator to unpack the elements of the tupletuplesand as...
