Let&#8217;s take the example of a declaration &#8220;x = 5&#8221;.<\/span><\/p><p><span style=\"font-weight: 400;\">In this case, Python creates an integer object containing the value 5 in memory, and then a reference named &#8220;x&#8221; that points to this object.<\/span><\/p><p><span style=\"font-weight: 400;\">Later, if you declare &#8220;y = x&#8221;, Python simply creates a new reference &#8220;y&#8221; that points to the same object as &#8220;x&#8221;.<\/span><\/p><p><span style=\"font-weight: 400;\">This means that any modifications made to &#8220;x&#8221; will also be visible through &#8220;y&#8221; because they both refer to the same object in memory.<\/span><\/p><p><span style=\"font-weight: 400;\">Understanding the difference between <\/span><b>value assignment and reference assignment<\/b><span style=\"font-weight: 400;\"> is very important. When you assign a simple variable such as an integer or a string to another variable, <\/span><b>Python performs a copy of the value<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><span style=\"font-weight: 400;\">As a result, modifications to one variable will not change the other. However, when <\/span><b>assigning complex variables<\/b><span style=\"font-weight: 400;\"> such as lists or dictionaries, Python performs <\/span><b>a reference assignment<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><span style=\"font-weight: 400;\">Thus, changes made to one variable will also be visible through the other variables that reference the same object.<\/span><\/p><p><span style=\"font-weight: 400;\">Furthermore, Python uses <\/span><b>scope mechanisms<\/b><span style=\"font-weight: 400;\"> to determine where a variable is accessible within a program. It can be local, global, or non-local depending on its position in the code.<\/span><\/p><p><span style=\"font-weight: 400;\">Once again, understanding these mechanisms is crucial.
