How to Convert Numeric String Range to a List in Python?

Python – Convert Numeric String Range to a List

To convert numeric string range like '4-9' to a list like [4, 5, 6, 7, 8, 9] in Python: split the string using hyphen as delimiter, convert the splits to integers, create a range using these integers, and then convert the range to a list.

Program

In the following program, we read a string from user using input() function, and convert the given numeric string range to a list.

# Take a numeric string range
x = '4-9'

# Split the string by hypehn
a, b = x.split('-')

# Convert string splits into integers
a, b = int(a), int(b)

# Create a range from the given values
result = range(a, b + 1)

# Convert the range into list
result = list(result)
print(result)

Output

4-9
[4, 5, 6, 7, 8, 9]
