Study Notes
String Formatting
- String formatting can be done with the
.format()
method - Example:
-
print('I study at {0} {1} and I am {2} years old.'.format(Uni_name_1, Uni_name_2, Age))
-
- Output:
-
I study at Khalifa University and I am 18 years old.
-
Literal Constants: Strings
- A string is a collection of characters
- Can be written using single quotes (
'HELLO'
) or double quotes ("HELLO"
) - Strings in double quotes are identical to strings in single quotes
Python IDE
- Use the IDE provided in Lab0 to run Python code.
- Example:
-
a = 4
-
b = 5
-
print(a > 1 or b > 1)
-
- Output:
True
Logical Operators
- The Logical NOT operator takes a single expression and negates the value.
- The Logical AND operator combines two or more expressions using the
and
keyword. - The Logical OR operator combines two or more expressions using the
or
keyword.
.format()
Method
- The
.format()
method can be used to format strings. - The order of arguments in the
.format()
method does not need to match the order in the string. - Example:
-
print('I study at {2} {0} and I am {1} years old.'.format(Uni_name_1, Uni_name_2, Age))
-
- This will print:
-
I study at 18 Khalifa and I am University years old.
