Using variables in Python
- In Python, a variable can be defined as following.
name = “Content”- In above code ‘name’ is the variable (or the name of the variable) and ‘Content’ is the content of the particular variable.
Numbers in variables in Python
- Numbers can be assigned to variables in Python as following.
number = 3- Also we can add numbers which are stored in variables as following.
- Use of any mathematical operator (+, -, *, /) is possible to calculate numbers stored variables.
number_a = 10
number_b = 2
print(number_a + number_b)
print(number_a * number_b)
print(number_a - number_b)
print(number_a / number_b)Combining variables in Python
- In Python, two variables can be combined by adding ‘+’ or ‘,’ in between them.
1. name = “Python”
2. type = “Language”
3. print(name + type)
4. print(name, type)- Line 3 output will be “PythonLanguage“.
- Line 4 output will be “Python Language“.
- To add a space between two text variables, we can use ‘comma (,)’ between them (Refer code 4 above) or we can do as in the following example.
print(name + “ ” + type)- To combine variables that contain different data types it is required to use ‘,’ between them.
- As an example, to combine different variable that contains a text and and numbers, it is required to use ‘,’ between them.
- If you use ‘+’ symbol to combine variables that contain different data types, it will result an error.
currency = “LKR”
amount = 100
print(currency, amount)
print(“Total is”, amount, currency)
