Python | Decimal step range in list

  • Last Updated : 03 Oct, 2019

Sometimes, while working with Python list we can have a problem in which we require to populate the list in a range of decimal. Integral ranges are easier to handle using inbuilt constructs, but having a decimal value to provide to range value doesn’t work. Let’s discuss a way in which this problem can be solved.

Method : Using list comprehension
One way to solve this problem is by using the list comprehension which can solve this problem in easier way by iterating the list and multiplying the range element to the index of element.

# Python3 code to demonstrate working of
# Decimal step range in list
# using list comprehension
# initializing start value 
strt = 5
# initializing step value 
step = 0.4
# using list comprehension
# Decimal step range 
test_list = [strt + (x * step) for x in range(0, 5)]
# Printing result
print("The list after decimal range value initialization : " + str(test_list))
Output :
The list after decimal range value initialization : [5.0, 5.4, 5.8, 6.2, 6.6]
