+"""
+Whitespace at the beginning of the line is called 'indentation'. These whitespaces or the indentation are very important in python. In a Python program,
+the leading whitespace including spaces and tabs at the beginning of the logical line determines the indentation level of that logic.
+
+* In most programming languages, indentation has no effect on progamming logic. It is used to align statements to make the code more readable.
+However, in python, indentation is used to associate and group statements.
+
+All statements within the same block must have the same indentation level. Typically, one tab or 4 spaces are used per level.
+
+All statements inside a block should be at the same indentation level.
+
+
+Below is the correct syntax for nested conditions with proper indentation:
+
+if <condition>:
+    -statements-
+    if <condition>:
+        -statements-

+# example:
+user  = int(input ("enter any digit.. "))
+if user<=10:
+    if user>=5: 
+        print("entered number is less than 10 and greater than 5")
+    else:
+        print("entered number is less than 5")
+else:
+    print("entered number is greater than 10")
