+# Conditionals
+# Python Conditions and If statements support the usual logical conditions
+#Equals: a == b
+#Not Equals: a != b
+#Less than: a < b
+#Less than or equal to: a <= b
+#Greater than: a > b
+#Greater than or equal to: a >= b
+
+#If statement:
+a = 33
+b = 200
+if b > a:
+  print("b is greater than a")
+Output:
+b is greater than a
+
+#The elif keyword is Python’s way of saying “if the previous conditions were not true, then try this condition”
+a = 33
+b = 33
+if b > a:
+  print("b is greater than a")
+elif a == b:
+  print("a and b are equal")
+Output:
+a and b are equal
+
+#The else keyword catches anything which isn’t caught by the preceding conditions.
+
+a = 200
+b = 33
+if b > a:
+  print("b is greater than a")
+elif a == b:
+  print("a and b are equal")
+else:
+  print("a is greater than b")
+Output:
+a is greater than b
+
+#Test if a is greater than b, AND if c is greater than a:
+a = 200
+b = 33
+c = 500
+if a > b and c > a:
+  print("Both conditions are True")
+Output:
+Both conditions are True
+
+#Test if a is greater than b, OR if a is greater than c:
+a = 200
+b = 33
+c = 500
+if a > b or a > c:
+  print("At least one of the conditions is True")
+Output:
+At least one of the conditions is True
+
+#Test if a is NOT greater than b:
+a = 33
+b = 200
+if not a > b:
+  print("a is NOT greater than b")
+Output:
+a is NOT greater than b
+#You can have if statements inside if statements, this is called nested if statements
+x = 41
+ 
+if x > 10:
+  print("Above ten,")
+  if x > 20:
+    print("and also above 20!")
+  else:
+    print("but not above 20.")
+Output:
+Above ten,
+and also above 20!
