#day_note .what is the use of continue statement in python?
,the continue statement is used to skip the rest of the code inside a loop and move on to the next iteration. When the continue statement is encountered, it immediately jumps to the next iteration of the loop without executing any further statements below it in the current iteration
for num in range(1, 6):
if num == 3:
continue
print(num)
Output:
1
2
4
5
In this example, the loop iterates over numbers from 1 to 5. However, when num equals 3, the continue statement is triggered, causing the program to skip printing that particular number and proceed to the next iteration.
The continue statement is commonly used when you want to skip certain iterations based on specific conditions or when you want to exclude certain elements from the loop's processing.

3. #day_note the upper, lower, and noscript methods in Python.
1. Upper Method:
The upper() method is used to convert all characters in a string to uppercase. It returns a new string with all uppercase letters. Here's an example:
python
string = "hello world"
uppercase_string = string.upper()
print(uppercase_string) # Output: "HELLO WORLD"
2. Lower Method:
The lower() method is the opposite of upper(). It converts all characters in a string to lowercase. Here's an example:
python
string = "Hello World"
lowercase_string = string.lower()
print(lowercase_string) # Output: "hello world"
3. Title Method:
The noscript() method is used to capitalize the first letter of each word in a string. It converts the first character of each word to uppercase and all other characters to lowercase. Here's an example:
python
string = "hello world"
noscript_string = string.noscript()
print(noscript_string) # Output: "Hello World"

1. Sorting a List using the sorted() Function:
- The sorted() function returns a new sorted list without modifying the original list.
- Syntax: sortedlist = sorted(originallist)
- Example: numbers = 5, 2, 8, 1, 9
sortednumbers = sorted(numbers)
print(sortednumbers) # Output: 1, 2, 5, 8, 9
2. Sorting a List in-place using the sort() Method:
- The sort() method sorts the list in-place, modifying the original list.
- Syntax: originallist.sort()
- Example: numbers = [5, 2, 8, 1, 9]
numbers.sort()
print(numbers) # Output: [1, 2, 5, 8, 9]
3. Sorting a List in Descending Order:
- Both the sorted() function and the sort() method can sort a list in descending order.
- Syntax: sortedlist = sorted(originallist, reverse=True)
originallist.sort(reverse=True)
- Example: numbers = 5, 2, 8, 1, 9
sortednumbers = sorted(numbers, reverse=True)
print(sortednumbers) # Output: 9, 8, 5, 2, 1
numbers.sort(reverse=True)
print(numbers) # Output: 9, 8, 5, 2, 1
