Basic syntax and arithmetic in Python and Ada are discussed and compared, including statement separators, block structure, and operators. A specific example shows the garnering of floating point input from the command line, rounding, and evaluation of an expression using basic arithmetic operators.Graham Morehead
These are two kinds of errors appear in python. Syntax error means you use some that the interpreter don't consider it to be vaild python syntax; while name error means that you use some name undefined. Numbers Python will turn integer to float when these two are persent in one formula. ...

Basic Python syntax Basic syntaxes can be referred to as simple guidelines that every programming language requires. Let's try to understand from our daily lives. Let's say you can't eat your food without having it dressed and placed properly on the platter. You need to have proper dressing...
解释器也可以使用如同编译器一般的文字分析器(lexical analyzer)和语法分析器(parser)然后再转译产生出来的抽象语法树(abstract syntax tree)。 可携性佳,直译式程序相较于编译式程序有较佳的可携性,可以容易的在不同软硬件平台上运行。而编译式程序经过编译后的程序则只限定于运行在开发环境平台。
Syntax errors will be picked up and reported on by the lexical analyser as statements are entered. Runtime errors will highlight the cause and the line number of the offending statement.The interpreter can be invoked as follows:$ python interpreter.py ...
