Given a string, we have to access characters from the string in Python.

Example:

    Input:
    str: "Hello world"

    Output:
    First character: H
    Second character: e
    Last character: d
    Second last character: l
    Characters from 0th to 4th index: Hello
    And, so on...

Program:

# access characters in string

# declare, assign string 
str = "Hello world"

# print complete string
print "str:", str

# print first character 
print "str[0]:", str[0]

# print second character 
print "str[1]:", str[1]

# print last character
print "str[-1]:", str[-1]

# print second last character
print "str[-2]:", str[-2]

# print characters from 0th to 4th index i.e.
# first 5 characters
print "str[0:5]:", str[0:5]

# print characters from 2nd index to 2nd last index
print "str[2,-2]:", str[2:-2]

# print string character by character
print "str:"
for i in str:
	print i,
#comma after the variable
# it does not print new line

Output

    str: Hello world
    str[0]: H
    str[1]: e
    str[-1]: d
    str[-2]: l
    str[0:5]: Hello
    str[2,-2]: llo wor
    str:
    H e l l o   w o r l d
