Python Repeat N Times

In this tutorial, you will learn how to repeat string n times with separator in Python.

Str = 'PYTHON' n = 2 lastchars = str-n: would make lastchars equal to 'ON' Step 2) The next step is to loop n time using a simple for loop and print out lastchars. Let me know if you get stuck I can help further. Since range data type generates a sequence of numbers, let us take the range in the place of sequence in the above syntax and discuss a few examples to understand the python for loop range concept. Keypoints About Range: range data type represents a sequence of numbers. Range(n) means it generates numbers from 0 to n-1. For the general 'repeat' part, you could use itertools.cycle. The complication is the 'merge the rest of the elements' part, though you can do that with islice, taking the next N-1 elements, and then advancing again to skip to the next element for the next loop.

Every day I love python more and more. Today, I was writing some code like: for i in xrange(N): dosomething I had to do something N times. But each time didn't depend on the value of i (. Numpy repeat repeats the elements of an array The NumPy repeat function essentially repeats the numbers inside of an array. It repeats the individual elements of an array. Having said that, the behavior of NumPy repeat is a little hard to understand sometimes.

First, you will take any string, in this case, I will use a variable called “string” to store our desired string and then we will use separators on the string.

In Python, you can use both double quotes and single quotes for the string and you can also use a single quote inside a double quote and vice-versa. Later on in our code, we will use the input() method and will store it in a variable say n.

this will take an integer as input and it will represent the amount of time we want to repeat our string. Now we will use “*” and this operator can be used to repeat the string as many numbers of times as you want, in this case, we want to repeat the string n times and then I will store the result in a variable say “repeated_string” and code for the same is:

After this, you will use a method knows as split(), this method splits up the complete string and then returns it as a list. The default separator is whitespace although you can take any separator you want. I will store this in a variable say “splitted_string” and the code for the same is:

although we don’t have to print this, if you print the code above then you will get the following output and this will help you understand how split() method works.

We can now use join function on the list that we obtained after using the split method, i.e on splitted_string. It just joins the elements and then returns it as a string after the elements have been joined by a separator. In this case, we will use separator as ‘-‘ although you can use anything you want in its place.

the output for the above code will be:

Note:- I have assumed the value of n to be 3 in the above example although you can take any value you want for n.

numpy.repeat() in Python

The numpy.repeat() function repeats the elements of an array.




The numpy.repeat() function consists of three parameters, which are as follows:

Python Repeat N Times

a: This parameter represents the input array.

Python repeat n times list

repeats: This parameter represents the number of repetitions for each element.

axis: It signifies the axis along which to repeat the values. By default, it uses the flattened input array, and returns a flat output array.


This function returns the output array (ndarray) which has the same shape as parameter ‘a’, except along the given axis.

Example 1

Python Repeat X Times

arr value:[01234]
