What arguments does print () expect in Python?
The print() function in Python is a fundamental function that displays output on the screen. It expects various types of arguments, which are used to specify what should be printed and how it should be printed.
By default, print() takes an optional argument, which is the object to be printed. If no argument is provided, it prints None, indicating the absence of any value. The most basic form of calling print() is:
print()
This will output:
None
In this case, the function is printing the result of the expression None.
Now, let's talk about the different types of arguments that can be passed to print():
String: You can pass a string as an argument to print(), which will display the text on the screen. For example:print("Hello, World!")
This will output:
Hello, World!
Variables: You can also pass variables as arguments to print(). Python will automatically convert the variable's value into a string and print it.name = "John"
age = 30
print(name)
print(age)
This code snippet will output:
John
30
List: If you pass a list as an argument, print() will display the elements of the list separated by spaces.numbers = [1, 2, 3]
print(numbers)
This will output:
[1, 2, 3]
Tuple: Similar to lists, if you pass a tuple as an argument, print() will display the elements of the tuple separated by spaces.colors = ("Red", "Green", "Blue")
print(colors)
This will output:
('Red', 'Green', 'Blue')
Dictionary: When you pass a dictionary as an argument, print() will display the key-value pairs in a readable format.person = {"Name": "John", "Age": 30}
print(person)
This will output:
{'Name': 'John', 'Age': 30}
Multiple Arguments: You can also pass multiple arguments to print(), which will separate them with spaces.name = "John"
age = 30
city = "New York"
print(name, age, city)
This code snippet will output:
John 30 New York
Formatted String: Python's f-string formatting feature allows you to embed expressions within string literals using curly braces {}. You can use print() with formatted strings.name = "John"
age = 30
print(f"{name} is {age} years old.")
This will output:
John is 30 years old.
In summary, print() expects various types of arguments in Python, including strings, variables, lists, tuples, dictionaries, and multiple arguments. You can also use formatted strings to customize your output.
