How do you join two strings without space in python?
How can I print my strings so that there are no spaces between each output. Show

1 use the separator parameter to the print function, to remove the space by passing in an argument with no space. Like this:
The default separator is a space. Specification is here: https://docs.python.org/3/library/functions.html#print answered Mar 14, 2016 at 8:19

They could be unstructured text, usernames, product descriptions, database column names, or really anything else that we describe using language. With the near-ubiquity of string data, it’s important to master the tools of the trade when it comes to strings. Luckily, Python makes string manipulation very simple, especially when compared to other languages and even older versions of Python. In this article, you will learn some of the most fundamental string operations: splitting, concatenating, and joining. Not only will you learn how to use these tools, but you will walk away with a deeper understanding of how they work under the hood. Splitting StringsIn Python, strings are represented as Have you guessed how those two features of strings relate to splitting functionality in Python? If you guessed that What about string immutability? This should remind you that string methods are not in-place operations, but they return a new object in memory. Splitting Without ParametersBefore going deeper, let’s look at a simple example: >>>
This is actually a special case of a Another feature of the bare call to >>>
The first thing to notice is that
this showcases the immutability of strings in Python: subsequent calls to The second—and the main—thing you should see is that the bare Specifying Separators
Where there are multiple consecutive separators (such as between “this” and “is” and between “is” and “my”), the first one will be used as the separator, and the subsequent ones will find their way into your result list as empty strings. Limiting Splits With Maxsplit

As you see above, if you set What happens
when you give a negative number as the
You were recently handed a comma-separated value (CSV) file that was horribly formatted. Your job is to extract each row into an list, with each element of that list representing the columns of that file. What makes it badly formatted? The “address” field includes multiple commas but needs to be represented in the list as a single element! Assume that your file has been loaded into memory as the following multiline string:
Your output should be a list of lists:
Each inner list represents the rows of the CSV that we’re interested in, while the outer list holds it all together. Here’s my solution. There are a few ways to attack this. The important thing is that you used
We call The first
element is What does The final part might be new: In all, we iterate through a list of strings, where each element represents each line in the multiline input string except for the very first line. At each string, we call Concatenating and Joining StringsThe other fundamental string operation is the opposite of splitting strings: string concatenation. If you haven’t seen this word, don’t worry. It’s just a fancy way of saying “gluing together.” Concatenating With the + OperatorThere are a few ways of doing this, depending on what you’re trying to achieve. The simplest and most common method is to use the plus symbol ( >>>
In keeping with the math theme, you can also multiply a string to repeat it: Remember, strings are immutable! If you concatenate or repeat a string stored in a variable, you will have to assign the new string to another variable in order to keep it. >>>
If we didn’t have immutable strings, Another note is that Python does not do
implicit string conversion. If you try to concatenate a string with a non-string type, Python will raise a >>>
This is because you can only concatenate strings with other strings, which may be new behavior for you if you’re coming from a language like JavaScript, which attempts to do implicit type conversion. Going From a List to a String in Python With .join()There is another, more powerful, way to join strings together. You can go from a list to a string in Python with the The common use case here is when you have an iterable—like a
list—made up of strings, and you want to combine those strings into a single string. Like This is a bit of a trick question. Remember that when you use >>>
Here, we join each element of the How could you make the output text more readable? One thing you could do is add spacing: >>>
By doing nothing more than adding a space to our join string, we’ve vastly improved the readability of our output. This is something you should always keep in mind when joining strings for human readability.

Using our web scraping tutorial, you’ve built a great weather scraper. However, it loads string information in a list of lists, each holding a unique row of information you want to write out to a CSV file:
Your output should be a single string that looks like this:
For this solution, I used a list comprehension, which is a powerful feature of Python that allows you to rapidly build lists. If you want to learn more about them, check out this great article that covers all the comprehensions available in Python. Below is my solution, starting with a list of lists and ending with a single string:
Here we use Tying It All TogetherWhile this concludes this overview of the most basic string operations in Python (splitting, concatenating, and joining), there is still a whole universe of string methods that can make your experiences with manipulating strings much easier. Once you have mastered these basic string operations, you may want to learn more. Luckily, we have a number of great tutorials to help you complete your mastery of Python’s features that enable smart string manipulation:
How do you concatenate two strings without space in Python?String Concatenation can be done using many ways.. Using + operator.. Using join() method.. Using % operator.. Using format() function.. Using , (comma). How do you add two strings without space?use the separator parameter to the print function, to remove the space by passing in an argument with no space. Show activity on this post. @BaileyFY: I've edited my answer to trim numbers as well. You've missed out str in str(random_number).
How do you not have a space in Python?Python String strip() function will remove leading and trailing whitespaces. If you want to remove only leading or trailing spaces, use lstrip() or rstrip() function instead.
How do I combine two strings in Python?Use the + operator
The + operator can be used to concatenate two different strings.
