Python — Common Errors and Methods :

Print() :

prints the result of expression to the console.

Eg : print(5+3) prints 8 to the console.

Type() :

Returns the data type of the variable/output .

Eg : print(type(9)) prints <class ‘int’> to the screen.

Note : We can convert float to int or int to float or to any datatype.

print(int(3.9)) returns 3

print(int(3.2)) returns 3

In the above example, we should notice that it will not round the value, it cuts the decimal part.

Whitespaces in Statements doesn’t matter Eg : print( 4 + 5 ) is same as print(4+5). 79 -99 characters has been set as a limit to increase readability in a statement.

Common Errors :

1)while True

print(“Hello World”)

This raises a Syntax Error because while statement should end in ‘:’ .

2) ZeroDivisionError :

print(5/0) — Whenever we try to divide a number by zero this type of error raises.
3) NameError :

print(4+spam) — This raises a NameError because the variable ‘spam’ is not defined.

4) TypeError :

print(5+ ‘5’) — It cannot convert ‘int’ to str implicitly.
