In Python, the print() function can take two optional parameters - end & sep - to specify what should be printed at the end of its arguments and between its arguments respectively.

If we execute the following code,

print('JavaScript')
print('React')

we will get the following output:

JavaScript
React

The outputs appear on separate lines because the print() function by default adds a newline character to the end of the string passed to it as the argument. However, we can use the end keyword argument to change the newline character to a different string value.

For example, if we pass an empty string to the end keyword argument, the newline character will not be printed. Instead an empty string will be printed and we will get both the outputs on the same line.

print('JavaScript', end=" ")

print('React')

# Output
JavaScript React

sep

Similarly, when we pass multiple string values to print(), the function will automatically separate them with a single space.

print('JavaScript', 'Python', 'C++')

#output
JavaScript Python C++

We can override the default separating string by passing a different string value to the sep keyword argument.

print('JavaScript', 'Python', 'C++', sep=" # ")

# output
JavaScript # Python # C++
