Questions on Strings and Arrays

  1. How to subtract a sub-string from a string? from front to back and back to front?

String follows index positions: 0, 1, 2, 3, 4, 5 etc. Minus calculates position from the last. Here the count starts from “-1”.

Str = 'Strings in Python'
Str[4]: n
Str[-3]:h
  1. How to write an array?

Array position starts from 0, 1, 2, 3, …..

import array as arr
my_array = arr.array('i', [76, 4559, 2100, 206, 235])
for i in my_array:
print('Array is: ', i)

Result:

Array is:  76
Array is: 4559
Array is: 2100
Array is: 206
Array is: 235

  1. How to use functions in String Manipulation?

You can use built-in functions to handle strings. Here is the best example:

Str = "Coding is fun"
print("Maximum alphabet: ", max(Str))
print("String in Center: ",Str.center(250))
substring = 'i'
print("Number of occurrences of substring in Str: ",
                  Str.count(substring))

Result

Maximum alphabet:  u
String in Center: Coding is fun
Number of occurrences of substring in Str: 2
