What Does [end=""] means python?
Question:
So I have been solving this problem on HackerRank and got stuck thinking about how to print the output of the problem on the same line. After that, I gave up and looked up the answer on the internet. Even though it worked all confused about how and why.

here is the Link of the Problem
I did reach this point and got stuck:
n = int(input())
for i in range(1, n+1):
print(i)
The output should be 123…n.
My Output was
1
2
3
.
.
.
n(every number on a new line)
The output should be in the same line.
So here is the required soln to the problem
n = int(input())
for i in range(1, n+1):
print(i, end="")
Can Anyone explain how it works? How did this , end="" changed the whole solution
Answers:
It means do not start a new line at the end of the print
By default, Python puts a newline character at the end of a print statement.
If you want, instead, to keep the output cursor on the same line, so you can print something afterwards, use end="". The next print statement will continue outputting on the same line.
print("Hello, ")
print("World!")
gives you
Hello,
World!
But
print("Hello, ", end="")
print("World!")
gives you
Hello, World!
Here is my evidence.
python adds a n’ (newline) character after each string if you use the print function. With the named argument end you can provide a custom last character, or a string, instead of ‘n’. So if end="" there will be nothing added to the end resulting in everything printed on the same line.
