Use list(range(10)) in 3.X.>>> l = range(10)>>> l[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]使用函数创建列表:>>> def display():... s1 = []... for i in range(9): # This is just to tell you how to create a list... ...
# create a list holding all the various data types defined above, including boolean. my_list = [test, instance, colors, False] print(my_list) Output Python Lists Are Ordered Sequences A Python list is an ordered collection of objects. The position of each item in a list is very importan...
We can store data of different data types in a Python list. For example, # a list containing strings and numbersstudent = ['Jack',32,'Computer Science']print(student)# an empty listempty_list = []print(empty_list) Run Code Using list() to Create Lists We can use the built-inlist(...
Method 1: Using the List Initializer The easiest and most fundamental way of creating a list and even a nested list is by using the list initializer notation “[ ]”. For the nested list, simply use the square brackets at the inside list again. To demonstrate this, let’s create a nest...
range函数用于创建数字列表 That may sound a little confusing. Let’s combine the range function with the list function to see exactly how this works. The range function doesn’t actually create a list of numbers; it returns an iterator, which is a type of Python object specially designed to...

Python Lists vs Arrays: How to Create Python Lists and Arrays A list in Python is simply a collection of objects. These objects can be integers, floating point numbers, strings, boolean values or even other data structures like dictionaries. An array, specifically a Python NumPy array, is sim...
This is different from other tools like R and Matlab that index elements within objects starting at 1. # Create a list of numbers:a= [1,2,3,4,5] Challenge - Extracting data What value does the code below return? a[0] How about this: ...
