This is the first index in a string.
a. –1
b. 1
c. 0
d. The size of the string minus one
Index denotes the characters within the string, and the first index will be 0.
Hence, the correct answer is option “C”.
Explanation of Solution
Indexing in string:
- The characters in a string could be accessed individually with an index.
- Each character has an index that would denote its position in the string.
- The example for string index is shown below:
- The index of the first character will be 0.
- The index of the last character in string is 1 less than the total characters in the string.
Syntax:
The syntax for iteration using indexing is shown below:
string_variable = ‘string_value’
variable = string_variable[index]
Explanation:
In the above syntax,
- The “string_variable” denotes the string that is accessed.
- The “index” denotes index of characters in the string.
- The expression “string_variable[index]” returns a copy of characters at index “index” in “string_variable”.
Example Program:
#Assign string to variable
name = 'Ike'
#Assign first character to variable
ch= name[0]
#Display result
print(ch)
Output:
I
In the above Python code, the first line assigns a string to variable “name”. In the second line, the first character of string is assigned to variable. In the third line, the result is displayed on the screen.
Explanation for incorrect options:
Index “-1”:
The index “-1” represents the last element in the string.
Hence, option “A” is wrong.
Index “1”:
The index “1” represents the last element in the string.
Hence, option “B” is wrong.
The size of string minus one:
The index “size of string minus one” denotes the index for the last element in the string.
Hence, option “D” is wrong.
