Sonal Yadav answered |
The slicing notation str[start:end] is used to extract a substring from a string. In this case, str[1:4] returns the characters at indices 1, 2, and 3, resulting in "yth".

Sonal Yadav answered |
The split() method is used to split a string into a list of substrings based on the specified delimiter. If no delimiter is provided, it splits the string at whitespace characters by default.
What will be the output of the following code?
str1 = "Hello"
str2 = "hello"

a)
True
b)
False
c)
Error: Case-sensitive comparison
d)
Error: Invalid syntax
|
|
Sonal Yadav answered |
String comparisons are case-sensitive in Python. In this case, "Hello" and "hello" are different strings, so the comparison str1 == str2 evaluates to False.

Sonal Yadav answered |
The slice notation [7:] returns a substring starting from index 7 until the end of the string. In this case, the output is "is fun".

Sonal Yadav answered |
The startswith() method is used to check if a string starts with a specified prefix. In this case, the output is False because the string "Python is fun" does not start with "Java".
What is the output of the following code snippet?
text = "Python is fun"
print(text.find("is"))- a)0
- b)2

Sonal Yadav answered |
The find() method returns the index of the first occurrence of a specified substring in a string. If the substring is not found, it returns -1. In this case, the substring "is" is found at index 7.

Sonal Yadav answered |
In Python, strings can be accessed using indexing. The index starts from 0, so str[7] refers to the character at index 7, which is "P".
What will be the output of the following code?
str = "Hello World"
print(str.split())- a)['Hello', 'World']
- b)Hello World
- c)['Hello World']
