New submission from Xinmeng Xia <[email protected]>:
For build-in function compile() in mode 'single', only single statement can be
well compiled. If we compile multiple statements, the parser will raise a
syntaxError. Seeing the following two programs, In program 1, 2 statement are
compiled. So the parser raises a Syntax error. It's the expected output.
However, if we insert a nested multi-line assignment in this code(see program
2), 3 statements are compiled. We expect the parser also raise a Sytax error.
But it' not.
Program 1 ( with expected results)
===================================
code1 = """
a = 1
b = 2
"""
c = compile(code1, "", "single")
===================================
Traceback (most recent call last):
File "/home/xxm/Desktop/nameChanging/report/test1.py", line 641, in <module>
c = compile(code1, "", "single")
File "", line 2
a = 1
^
SyntaxError: multiple statements found while compiling a single statement
Program 2 (with unexpected results)
=================================
code2 = """
c ='''
d=1
'''
a = 1
b = 2
"""
c = compile(code2, "", "single")
=================================
Expected out for program 2: Raise a syntaxError too， But it's not.
