@Python_Dv B. ell
x[1:4] means start at index 1, stop before index 4.
H-e-l-l-o
0-1-2-3-4
So you get positions 1, 2, 3 = "ell"
Python slicing: the end is never included.
English
@Python_Dv Output is B) ell.
Reason (quick): Python slicing is start inclusive, end exclusive.
"Hello"[1:4] → indexes 1,2,3 → e l l.
English
Ans---- (B) ell
The code snippet uses Python's string slicing feature. In Python, strings are zero-indexed, meaning the first character has an index of 0.
x = "Hello" assigns the string "Hello" to the variable x. The indices are:
H: 0
e: 1
l: 2
l: 3
o: 4
print(x[1:4]) uses slicing [start:end]. The slice includes the character at the start index (inclusive) up to, but not including, the character at the end index.
Therefore, x[1:4] extracts the characters from index 1 up to (but not including) index 4, which are 'e', 'l', and 'l'.

@Python_Dv Answer: (B) ell
The code uses Python's string slicing feature.
x = "Hello" assigns the string "Hello" to the variable x.
print(x[1:4]) attempts to print a substring of x.
String indices in Python start at 0. The string "Hello" has indices as

@Python_Dv Answer: B) ell
Slicing [1:4]:
› Start: index 1 = 'e'
› Stop: before 4 (gets 1,2,3)
› Result: 'ell'
For beginners: Stop index is exclusive! [1:4] gets indices 1, 2, 3 but NOT 4.
English
Stop guessing and start indexing! 🐍
The answer is B: ell.
Common mistakes to avoid:
❌ Thinking it starts at 1: Python starts at 0. x[0] is 'H'.
❌ Including the stop index: Slicing is always inclusive:exclusive. It stops before the 'o'.

@Python_Dv D - Error. This is due to a syntax error by the omission of the closing square bracket, otherwise the answer should have been "B-ell", python slicing method.
English
@Python_Dv B - 1:4 starts at one and ends at 3 (the 4 is exclusive) in most programming, indices are 0 based, so 0 is the first element "H" and 1 is the second "e".
But one issue, why didn't you use "Hello World!" I feel slightly offended you didn't greet the programming world correctly...
English
@Python_Dv B) ell us the right answer
Here we are using the concept of list slicing [start: end: step_size] and by default stepsize is 1 and end excluding so answer is ell.
English
@Python_Dv print(x[1:4)
File "<stdin>", line 1
print(x[1:4)
