Blocks in python does not use braces, for blocks we use indentation

Statement in python does not end with semicolon, each line shows a separate statement                     If we want to write statement in multiple line we can use line continuation symbol(\),                       statement contains []{}() does not need line continuation symbol

Comments is created by using # symbol

String         can be placed in ‘’ or “” or(triple) ‘’’    ‘’’ or “””      “”” , triple is used when string                      exists in more than 1 line
