## Creating list of five elements from a List of Number in Python

python create empty list
create a list of 5 elements python
nested list python
python create list with n elements
python list
list function python
python append list to another list
python create new list of size

i'm using Python 3.7.

I have a tuple of Numbers like this:

``` x = ((1,2,3,4,5,6,7,8,9....etc))
```

I would Like to obtain a list of list divided by 100 and with Five numbers from the list in an iterative way... something like this:

```[[[0.0], [0.01], [0.02], [0.03], [0.04]],
[[0.01], [0.02], [0.03], [0.04], [0.05]],
[[0.02], [0.03], [0.04], [0.05], [0.06]],
[[0.03], [0.04], [0.05], [0.06], [0.07]],
[[0.04], [0.05], [0.06], [0.07], [0.08]],
[[0.05], [0.06], [0.07], [0.08], [0.09]],... etc
```

I Tried this but it doesn't work properly:

```Data = [[[(interest_over_time_data+j)/100] for
interest_over_time_data in range(5)]for j in
interest_over_time_data]
```

The real numbers are not a list of consecutive number so I cannot add +1 to each element...

Python lists - working with lists in Python, It creates a list containing five elements. \$ ./simple.py It contains numbers, a boolean value, another list, a string, a tuple, a custom object, and a dictionary. \$ . A list of random numbers can be then created using python list comprehension approach: >>> l = [random.randint (0,10) for i in range (5)] >>> l [4, 9, 8, 4, 5] Another solution is to use randrange function (except that can specify a step if you need):

You can use 3rd party NumPy for an array-based solution:

```import numpy as np

first_row = np.arange(5) / 100
first_col = np.arange(10) / 100

res = first_row + first_col[:, None]

array([[ 0.  ,  0.01,  0.02,  0.03,  0.04],
[ 0.01,  0.02,  0.03,  0.04,  0.05],
[ 0.02,  0.03,  0.04,  0.05,  0.06],
[ 0.03,  0.04,  0.05,  0.06,  0.07],
[ 0.04,  0.05,  0.06,  0.07,  0.08],
[ 0.05,  0.06,  0.07,  0.08,  0.09],
[ 0.06,  0.07,  0.08,  0.09,  0.1 ],
[ 0.07,  0.08,  0.09,  0.1 ,  0.11],
[ 0.08,  0.09,  0.1 ,  0.11,  0.12],
[ 0.09,  0.1 ,  0.11,  0.12,  0.13]])
```

11. Lists, The values that make up a list are called its elements, or its items. There are several ways to create a new list; the simplest is to enclose the elements in square brackets numbers[9-8] 5 >>> numbers[1.0] Traceback (most recent call last): File That's why Python is free to alias strings (and any other immutable kinds of  In Python programming, a list is created by placing all the items (elements) inside square brackets [], separated by commas. It can have any number of items and they may be of different types (integer, float, string etc.). A list can also have another list as an item. This is called a nested list.

Love one line solutions:

```[[[x[p]/100] for p in range(k,k+5)] for k in range(len(x)-4)]

#>[[[0.01], [0.02], [0.03], [0.04], [0.05]],
#> [[0.02], [0.03], [0.04], [0.05], [0.06]],
#> [[0.03], [0.04], [0.05], [0.06], [0.07]],
#> [[0.04], [0.05], [0.06], [0.07], [0.08]],
#> [[0.05], [0.06], [0.07], [0.08], [0.09]]]

Python List, Creating a list with multiple distinct or duplicate elements. A list may contain duplicate values with their distinct positions and hence, multiple distinct or duplicate  In this article, you’ll learn about Python arrays, difference between arrays and lists, and how and when to use them with the help of examples. In programming, an array is a collection of elements of the same type. Arrays are popular in most programming languages like Java, C/C++, JavaScript and so on. However, in Python, they are not that

Okay, you want your output containing lists with a length of 5 shifting from the first element of `x` to the last. Therefore your output will contain `n-4` lists, where `n` is `len(x)`.

So first we need to iterate over `range(len(x)-4)`

Then we want five elements from `x` starting at a given offset `i`. We can use slicing for this, e.g. `x[i:i+5]`.

And we want all elements of this sublist divided by `100`.

All together packed in list comprehension it looks like this:

```x = (1,2,3,4,5,6,7,8,9)
res = [
[j/100.0 for j in x[i:i+5]]
for i in range(len(x)-4)
]
print(res)
```

Which results in

```[[0.01, 0.02, 0.03, 0.04, 0.05],
[0.02, 0.03, 0.04, 0.05, 0.06],
[0.03, 0.04, 0.05, 0.06, 0.07],
[0.04, 0.05, 0.06, 0.07, 0.08],
[0.05, 0.06, 0.07, 0.08, 0.09]]
```

Or if you want to have `0.0` as in your example output:

```x = (1,2,3,4,5,6,7,8,9)
x = [0] + list(x)
res = [
[j/100.0 for j in x[i:i+5]]
for i in range(len(x)-4)
]
print(res)
```

Python, While working with the Python lists, we can come over a situation in which we The original list is : [4, 5, 6, 3, 9] The list after adding K to each element : [8, 9, 10,​  • We create a list by using the square brackets. •alist = [1, 3.5, “hello”] • A list with three elements of three diﬀerent types •blist = [1, 3.5, “hello”, 1] • A list with four elements, where one element is repeated •clist = [1, “hello”, 3.5] • A diﬀerent list than alist, but with the same elements • The order

List in Python : lists, range, slice, append, len, etc in Python, For example, in the list [3,4,2,5] , index will start from 0. So, index of 3 is 0, list in python. So, to access any element of a list, we write name_of_list[index]. [1, 3, 5​, 7, 9]. range(1,10,2) will create a sequence of numbers but with a step of 2. Python module itertools has a function called repeat, which can be used to get a list repeating single element n times. If we want to create a list repeating number 5, ten times we can use itertools.repeat function as follows. import itertools. itertools.repeat (5, 10) itertools.repeat function yields an iterator not a list. So to get a list we

Lists, The values in list are called elements or sometimes items. There are The one-​eth element of numbers, which used to be 123, is now 5. You can In this example, Python only created one string object, and both a and b refer to it. But when  Here, a[1] = 5 will simply make the element at the 1 st index of 'a' 5. Lists are mutable → It means that we can change the value of any member of the list as we have done above (a[1] = 5). It is not necessary in Python for the list to contain only the same type of elements. We can also have a list as shown in the example given below: Python

Python: Generate and print a list of first and last 5 elements where , Write a Python program to generate and print a list of first and last 5 elements where the values are square of numbers between 1 and 30 (both  In Python the items or elements of the list can be accessed by using the index operator that is []. The index operator directly refers to the element. The index of a list is started from 0 and when we have to access the 4 th item of the list then we will write 3 as the index value. A list of 4 items or elements will have the items from 0 to 3.
