+Modules can be imported in the following ways:
+
+1. import module_name
+    This will import the mosule but if when you will use the function from the module,
+    you have to specify the module_name with the function. e.g: user_module.function1()
+
+2. import module_name as short_name
+    This is exactly similar to the previous method. The only difference is that instead
+    of writing the module_name again you can use the short_name you gave.
+    e.g: import user_module as um
+         um.function1() 
+
+3.  from module_name import function
+    This will import only the specific function from the given module. You cannot use other
+    functions from that module. 
+    e.g: from user_module import function1
+         function1()
+
+4. from module_name import *
+    This will import all the functions from the module. Additionally you will not need to 
+    write the module_name anymore for accessing the functons.
+    e.g: from user_module import *
+         function1()
+

+#import user_module
+#import user_module as um
+#from user_module import functon1
+from user_module import *
+import random
+
+
+functon1()
+functon2()
+
+
+x = random.randrange(1,100) #it will generate a random number within 1 to 100. Function imported from random module.
+print(x)
+
+# dir(module_name)
+# help(mosule_name)
+
+# The following will show the dir where python search for modules
+import sys
+print(sys.path)
+
+#sys.path.append("your_module_path")        this will add your own module path to predefines paths od python modules
