A print() can continue in the next line by using a backslash (\). For example:
>>>print("Come and \ Backslash at the end does not
complete your work", end='###')
Output: allow the print() to terminate
Come and complete you work###
1. Which statement is included but not executed in the program?
2. In a Python program, which function is used to accept input from a user?
3. What will be the output produced on the execution of the following statement?
>>> print('Two','plus','two', sep='#',end=' is four')
Common Errors
Using keywords as variable names
if = 10 → if is a keyword
Missing quotation marks for strings
print(India) → string value not enclosed in quotation marks
Using different quotation marks to mark the beginning and end of a string
print('India')
print('India")
→ the string should be enclosed within the same type of quotation marks
Missing the closing parenthesis
print(10 → missing ')'
Using incorrect case of a letter: Print / PRINT
PRINT('INDIA') → it should be print()
Let's Summarise
Ø The character set of Python includes lowercase and uppercase alphabets, digits, symbols, whitespace
characters, and some special characters like _ *$.,?. While naming the objects, the underscore character is
used like an alphabet.
Ø The smallest unit of a program is known as a token or a lexical unit.
Ø The tokens in Python are keywords, identifiers, literals, delimiters, and operators.
Ø Keywords are reserved words that have a specific meaning for the Python interpreter/compiler.
Ø Identifiers are the names or labels used to name a string, number, function, etc., in a program.
Ø The name should begin with an uppercase alphabet, lowercase alphabet, or underscore (_).
Ø An identifier cannot contain any special symbol except an underscore.
Ø A literal denotes a value, also called an object. Examples of literals include 23, 234.67, 'Hello',
and "How are you".
Ø Delimiters are symbols that are used to separate data items.
Ø An operator performs a specific operation on the specified values. For example, in the expression 23+4, the
operator + denotes the addition of the adjacent operands 23 and 4.
