• Project Abstract: All phases of a compiler for Python Language till intermediate code optimisation have been implemented using C language, while target code generation has been implemented using Python language. The constructs 'if-else' and 'while' have been handled. Syntax and Semantic Errors have been handled and panic mode recovery has been implemented in the lexer. Optimisation techniques used are constant propagation and packing temporaries.
• **Code Execution: **

1. The following commands can be used to execute the code in any of the folders except '5-Target_Code':

lex proj.l
yacc -d -v proj1.y
gcc lex.yy.c y.tab.c -ll -lm -w
./a.out

2. The following commands execute the code in the '5-Target_Code' folder:

python3 final.py

Various folders

1. 1-Token_And Symbol_Table: This folder contains the code that outputs the tokens and the symbol table.
2. 2-Abstract_Syntax_Tree: This folder contains the code that displays the abstract syntax tree.
3. 3-Intermediate_Code_Generation: This folder contains the code that generates the symbol table before optimisations and the intermediate code.
4. 4-Optimised_ICG: This folder contains the code that generates the symbol table after optimisations, the quadruples table and the optimised intermediate code.
5. 5-Target_Code: This folder contains the code that displays the assembly code/target code.
6. Entire_Compiler: This folder contains the code that generates the all the above outputs at once and displays it on the terminal.
