Lexer(词法分析程序)可以将源代码拆分为几个单词

What is Parser? !

什么是Parser(语法、语义分析程序)

The parser can parse the tokens split by the lexer.
Parser(语法、语义分析程序)可以解析由Lexer(词法分析程序)拆分的单词

For Example?

NO.ONE

variable = expr(if expr)
            /    \
      expr (+|-) expr(if expr)
      /             \
expr (*|/)expr      expr (*|/)expr
(if expr)           (if expr)
for example variable = 0*4
AST be like this one:
variable = expr
         /    \
        0 + expr //can delete
           /   \
          0 *   4 

NO.TWO

print(sth)
    /    \
data[sth]   sth
(if variable) (if expr)
for example expr = "something"
AST be like this one:
print(sth)
       |
       "something"
console:
       something
