[Basic Grammar] Python Strings: Slicing Strings

• Slicing 

You can return a range of characters by using slice syntax and should specify the start index and end index.

 

Example 

Get the characters from position 1 to position 3 (not included):

b = "Hello, World!"
print(b[1:3])

 

• Slice from the Start 

b = "Christmas"
print(b[:5])

 

• Slice to the End 

b = "Christmas"
print(b[:8])

 

• Negative Indexing 

b = "Hello, World!"
print(b[-5:-2])

 

Exercises 

Please solve the following code.

text = "Hello, World!"
reversed_text = text[::-1]
print(reversed_text)

!dlroW ,olleH

In this code, the first ':' indicates the beginning of the slice. The empty space before the second ':' means the slice starts from the beginning of the sequence. '-1' specifies that the slice goes up to the end of the sequence in reverse order.
