Method # 1: Using List Comprehension + zfill()
A combination of the above functions can be used to accomplish this task. In this we perform the task of adding numbers using a list comprehension, and zfill () takes care of the length required for each line.
| # Python3 code to demonstrate how it works
# Construct N Range Equilength String list
# using a list comprehension + zfill ()
# initialize N N = 6
# print N print ( " Number of elements required: " + str (N))
# initialize K K = 3
# Construct N Range Equilength String list
# using a list comprehension + zfill () res = [ str (ele) .zfill (K) for ele in range (N)]
# print result print ( "K Length range strings list:" + str (res)) |
Output:
Number of elements required: 6 K Length range strings list: [’000’,’ 001’, ’002’,’ 003’, ’004’, ’005’]
Method # 2: Using map () + string formatting
This task can also be done using the above functions. In this, we extend the length logic using string formatting. And it is used to plot the N range.
| # Python3 code to demonstrate how it works
# Construct N Range Equilength String list
# using map () + string formatting
# initialize N N = 6
# print N print ( "Number of elements required: " + str (N))
# initialize K K = 3
# Construct N Range Equilength String list
# using map () + string formatting temp = ’{: 0’ + str (K) + ’}’ res = list ( map (temp. format , range (N)))
# print result print ( "K Length range strings list:" + str (res)) |
Output:
Number of elements required: 6 K Length range strings list: [’ 000’, ’001’,’ 002’, ’003’,’ 004’, ’005’]
