New submission from Vincent Liang <shenhen...@qq.com>:
Strange behavior is found when lambda is used inside for-loop.
code:(same as attached file)
# begin of CODE
def aa(x):
print("aa")
def bb(x):
print("bb")
namefun = [
("a", aa),
("b", bb),
]
name2fun = {}
for name, fun in namefun:
name2fun[name] = lambda x: fun(x)
# issue happened when calling lambda
name2fun["a"](1)
name2fun["b"](1)
# end of CODE
output:
bb
bb
expected output:
aa
bb
