What is The Difference ❓ Comment The Answer 📷🔥

@PythonPr Python is the only place where 'x' and 'X' are more different than my ex and me." 🐍💀

@PythonPr The ✓ version should work because the variable 'x' is consistent. The × version will fail at the end because its attempt to print(X) changes to uppercase, not the same as it's prior use in lower case.

@PythonPr X is capital in second one. @grok am i correct ?

@PythonPr Case sensitive - In python x is not equal to X 😎

@PythonPr Capital X.

@PythonPr You are asking to print the value of X which does not exist in the code.

@PythonPr Top: prints [1, 2, 3, 4] — y = x means both names point to the same list, so append() mutates it in place. Bottom- NameError (X is not defined). Python is case-sensitive.

@PythonPr Print(X) is supposed be print(x) with x in small letter in the second case

@PythonPr X . x !

@PythonPr Use of wrong cases. Upper case is used to print when the variable x is on a lower case.

@PythonPr In second X is used rather than x

@PythonPr print (X) instead of print(x)

@PythonPr print(x) works because Python is case-sensitive. X is a different variable.

@PythonPr print(X) Undeclared variable. .@PythonPr

@PythonPr La variable passée en argument de la fonction print du second cas est en majuscule. Python est sensible à la casse.

@PythonPr Case sensitive x !=X

@PythonPr Capital X

@PythonPr You are printing upcase X when it should not be

@PythonPr print(x) is correct because the “x” within parentheses is supposed to be lower case

@PythonPr Case sensitivity issue

@PythonPr in-correct casing of the "x" variable
