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)
Array is: 76
Array is: 4559
Array is: 2100
Array is: 206
Array is: 235
- 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))
Maximum alphabet: u
String in Center: Coding is fun
Number of occurrences of substring in Str: 2
