In Python, you can use '''  some comments '''' or " " " some comments " " "  using triple quotes for multi-line comments.
# is used for single-line comments.
For Examples:
" " "
print('This is an example of multi-line comment')
print('This is how all the statements will be treated as comments')
" " "
a=10
b=20
sum = a + b
print('Result is:' sum)
#this is a single-line statement.
#this is another comment 
Thus, we can use # for single-line comments also for multiple comments.
