We need to call functions. There are several functions in Python like the print() function. - Round brackets are used with a function to pass a parameter in it. - We can define our own functions as well. #5 - Concatenation is used to combine two things like we can convert two strings into one using concatenation. - Concatenation is done using the (+) operator. e.g., 'navin' + 'navin' - Repetition is used to print a single value multiple times like we can print a string like "Navin" multiple times. - Repetition is done using the (*) operator. e.g., 'navin' * 3 #6 - (\n) has a special meaning in Python. It is used to enter a new line. - To print the original string or to neglect the meaning of \n, we have to use a Raw String. - Raw string is a string that returns it as it is without making any changes to it. - We have to specify (r) before the quote to print the same string that is present inside the quotes. #Python #telusko Github :- https://github.com/navinreddy20/Python- More Learning : Java :- https://bit.ly/3x6rr0N Python :- https://bit.ly/3GRc7JX Django :- https://bit.ly/3MmoJK6 JavaScript :- https://bit.ly/3tiAlHo Node JS :- https://bit.ly/3GT4liq Donation: PayPal Id : navinreddy20
