ASCII Shift for String Transformation

Write a Python program to find a string which, when each character is shifted (ASCII incremented) by shift, gives the result.

ASCII table -

Input:
Ascii character table
Shift = 1
Output:
@rbhhbg`q`bsdqs`akd

Input:
Ascii character table
Shift = -1
Output:
Btdjj!dibsbdufs!ubcmf

Sample Solution-1:

Python Code:

# License: https://bit.ly/3oLErEI

def test(strs, shift):
    # Joining characters after shifting them by the specified amount
    return "".join(chr(ord(c) - shift) for c in strs)

# Example 1
strs1 = "Ascii character table"
print("Original string:")
print(strs1)
shift1 = 1
print('Shift =', shift1)
print("A new string which, when each character is shifted (ASCII incremented) by shift in the said string:")
print(test(strs1, shift1))

# Example 2
strs2 = "Ascii character table"
print("\nOriginal string:")
print(strs2)
shift2 = -1
print('Shift =', shift2)
print("A new string which, when each character is shifted (ASCII incremented) by shift in the said string:")
print(test(strs2, shift2))

Sample Output:

Original string:
Ascii character table
Shift = 1
A new string which, when each character is shifted (ASCII incremented) by shift in the said string:
@rbhhbg`q`bsdqs`akd

Original string:
Ascii character table
Shift = -1
A new string which, when each character is shifted (ASCII incremented) by shift in the said string:
Btdjj!dibsbdufs!ubcmf

Sample Solution-2:

Python Code:

# License: https://bit.ly/3oLErEI

def test(strs, shift):
    # Using list comprehension to generate a list of characters after shifting
    shifted_chars = [chr(ord(strs[i]) - shift) for i in range(len(strs))]
    # Joining the characters to form the final shifted string
    return "".join(shifted_chars)

# Example 1
strs1 = "Ascii character table"
print("Original string:")
print(strs1)
shift1 = 1
print('Shift =', shift1)
print("A new string which, when each character is shifted (ASCII decremented) by shift in the said string:")
print(test(strs1, shift1))

# Example 2
strs2 = "Ascii character table"
print("\nOriginal string:")
print(strs2)
shift2 = -1
print('Shift =', shift2)
print("A new string which, when each character is shifted (ASCII decremented) by shift in the said string:")
print(test(strs2, shift2))

Sample Output:

Original string:
Ascii character table
Shift = 1
A new string which, when each character is shifted (ASCII incremented) by shift in the said string:
@rbhhbg`q`bsdqs`akd

Original string:
Ascii character table
Shift = -1
A new string which, when each character is shifted (ASCII incremented) by shift in the said string:
Btdjj!dibsbdufs!ubcmf
