Q1. Convert a given string to int using a single line of code.
Example:
If the string is "108", it should be converted to the integer 108.
Code:
a = ‘9’
print (int(a))
Explanation:
In Python, you can convert a string that represents a number to an integer using the built-in int() function. This is a straightforward and efficient way to perform the conversion in a single line of code.
a = ‘9’
print (int(a))Q2. Write a code to convert a string to a list.
Example:
Let’s say you have the string "hello" and you want to convert it to a list of its characters. Then output should be [‘h’, ‘e’, ‘l’, ‘l’, ‘o’]
Code:
string = “hello”
char_list = list(string)
print(char_list)
Explanation:
The list () function is a built-in function in Python that converts an iterable (like a string) to a list.
The function takes a single argument, which in this case is the string "hello"
The list() function processes the string and converts it to a list where each character of the string becomes a separate element in the list.
string = "hello"
char_list = list(string)
print(char_list)
Q3. Write a code to reverse a string.
Example:
Let’s say you have the string "hello" and you want to reverse it.
Then output should be olleh
Code:
reversed_string = “hello”[::-1]
print(reversed_string)
Explanation:
Slicing allows you to access a subset of a sequence (like a string) by specifying a start, stop, and step.
Slice notation [::-1] means “start from the end of the string and move backwards by one step at a time” until you reach the beginning.
reversed_string = "hello"[::-1]
print(reversed_string)
