Basic text in Python
- To print on python,
print(“Text”)- In python a text should always be a “String”, and it should be inside “”.
- To combine two text strings together, a ‘+’ sign is always required. And the two strings need to be always inside “”.
print(“Hello ” + “Python”)- Python does not support ‘&’ when combining two text strings. (Only ‘+’ is valid.)
- Alternatively a comma also can be used to combine two strings.
- But when using a comma, it will automatically add a space between those two strings.
- Adding a space manually before or after any string is not required with comma.
print(“Hello”, “Python”)Numbers in Python
- When we need to display numbers in python, numbers can be interpreted without “” as just numbers.
print(3)- Numbers can be calculated in print function (Using +, -, / & *)
print(1 + 2)- Python uses BODMAS to calculate numbers.
- When combining a text string and a number (Not a string, just a plain number) in python, a comma is always the right thing. In this case adding ‘+’ between a test string and a number (Without “”) gives an error.
- But if we consider the number as a string by adding “”, ‘+’ will definitely work.
Special operators in Python
- When // is added between two numbers it rounds down the division to a whole number.
- Actually, when // is used it gives the largest integer as the output.
print(9//3) [E.g.: Output is 3]
print(10//3)
print(16//3)
print(100//6)- When % added between two numbers it displays the remainder.
print(4%2) [E.g.: Output is 0]
print(3%2)
print(10%6) - The operators // and % works similar to division but they gives different outputs.
