range() to a list in Python
Often times we want to create a list containing a continuous value like, in a range of 100-200. Let’s discuss how to create a list using the range()
function.
Will this work ?
My_list = [ range ( 10 , 20 , 1 )]
print (My_list)
|
Output :
As we can see in the output, the result is not exactly what we were expecting because Python does not unpack the result of the range() function.
Code #1: We can use argument-unpacking operator i.e. *.
My_list = [ * range ( 10 , 21 , 1 )]
print (My_list)
|
Output :
As we can see in the output, the argument-unpacking operator has successfully unpacked the result of the range function.
Code #2 : We can use the extend()
function to unpack the result of range function.
My_list = []
start, end = 10 , 20
if start < end:
My_list.extend( range (start, end))
My_list.append(end)
print (My_list)

Output :
