End Variable, Formatting output

End Variable In Python

In Python, the end parameter is used with the print() function to specify what character(s) should be printed at the end of the output. By default, the end value is set to \n, which represents a newline character, causing the next output to appear on a new line.

Here's an example:

print("Good Evening", end="\n")
print("Hello Everyone")

Output

Good Evening
Hello Everyone

In the above example, the first line prints Good Evening with the end value set to \n, which produces a newline. The second line then prints Hello Everyone on a new line.

You can change the end value to any character or string you want. For instance:

print("Good Evening" , end=" ")
print("Hello Everyone")

Output

Good Evening Hello Everyone

In this example, we set the end value to a space character " ", which results in both strings being printed on the same line with a space between them.

The format() Function in Python

The format() function in Python is used to format strings by replacing placeholders with corresponding values. Placeholders are represented by curly braces {} within the string, and the format() function replaces them with the provided values.

Here's an example:

x="Sakshi"
y=21
dob= "07/10/2001"
print("Hello {} .Your Age is {} .Your DOB is {}". format(x,y,dob))

Output

Hello Sakshi. Your Age is 21. Your DOB is 07/10/2001.

In this example, we have three variables: x, y, and dob, containing the values Sakshi, 21, and 07/10/2001, respectively. The format() function is used to inject these values into the string. The {} placeholders are replaced with the corresponding values in the order they appear in the format() function..

If you change the order of the variables in the format() function, the output will reflect that change:

x="Sakshi"
y=21
dob= "07/10/2001"
print("Hello {} .Your Age is {} .Your DOB is {}". format(y,dob,x))

Output

Hello 21. Your Age is 07/10/2001. Your DOB is Sakshi .

In this example, the variable sequence in the format() function is changed, resulting in the values being printed in a different order.

To avoid confusion when the variable sequence is changed, you can assign names to the placeholders and use those names in the format() function:

x="Sakshi"
y=21
dob= "07/10/2001"
print("Hello {place1} .Your Age is {place2} .Your DOB is {place3}". format(place3=dob,place2=y,place1=x))

Output

Hello Sakshi. Your Age is 21. Your DOB is 07/10/2001.

In this example, we assign names to the placeholders place1, place2, place3 and explicitly specify which value should be placed in each position using keyword arguments in the format() function. This way, the output remains consistent even if the variable sequence is changed.
