Lines and Indentation
Lines and Indentation:
In Python, lines and indentation are significant and are used to indicate the structure and scope of the code.The number of spaces or tabs used for indentation should be consistent throughout the entire code block. Typically, four spaces are used for each level of indentation, although some developers prefer to use a different number of spaces or tabs.
For example, the following code block uses indentation to define the scope of the if-else statement:
def print_numbers():
for i in range(10):
if i % 2 == 0:
print(i, "is even")
else:
print(i, "is odd")
In this code, there are several lines that are indented to indicate that they are part of a code block. The for loop and the if-else statement both have indented blocks of code, and the print statements are indented within those blocks.
It’s important to note that in Python, the use of whitespace is significant. The number of spaces or tabs used for indentation should be consistent throughout the entire code block. Typically, four spaces are used for each level of indentation, although some developers prefer to use a different number of spaces or tabs.
In addition, blank lines can be used to separate logical sections of code or to make the code more readable. However, it’s important not to overuse blank lines, as this can make the code harder to read by breaking up its logical flow.
