This article shows you how to name slices in python. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Name slice object

The commonly used slicing method is to use the index to control the beginning and end. As follows:

1record = '.170.60.'

2print (f "height {record [20:23]}, weight {record [31:33]}") # height 170, weight 60

Because we use index numbers to control slices, this makes the code difficult to read and only see the numeric subscript. So to make the code easier to read, we can use sliced objects and the slice () function:

1record = '.170.60.'

2print (f "height {record [20:23]}, weight {record [31:33]}") # height 170, weight 60

3height = slice (205.23)

4weight = slice (31 cam 33)

5print ("height {}, weight {}" .format (recordheight, weight))

Above, slice (start, stop, step) is used to generate sliced objects and assign variables. Variable slicing objects make the code easier to understand. Readers do not have to pay attention to the location of the source string corresponding to the index when they read the code again. This way of naming sliced objects is easier to read.

The parameter step refers to the step size.

Generally speaking, if a large number of hard-coded subscript values appear in the code, the readability and maintainability will be greatly reduced. For example, if you look back at the code you wrote a year ago, you will touch your head and wonder what you wanted to do at that time. The solution here is a very simple way for you to express more clearly what the code is going to do. The built-in slice () function creates a slice object that can be used wherever slices are allowed. For example:

1items = ["h",'e-maths, girls, girls, boys, girls, girls

2a = slice (2pc7)

3print (items [a]) # = = items [2:7]

4items [a] = "12345" # string assignment, slice is a string

5print (items)

6items [a] = ['axiomagy'] # list element assignment, slice is a tuple

7print (items)

eight

Slicing object

10a = slice (1, 1010, 2) # start, end,step

11print (items [a])

12print (a. Print. A. Stop. Step) # start1 10 2
