This a date validation program and I got the 'Leading 0 not permitted' error at the highlighted part though I haven't used '01' anywhere:
if (eval(dmy_split[0])>=1 and eval(dmy_split[0])<=12 and eval(dmy_split[1])>=1 and eval(dmy_split[1])<=12 or len(dmy_split[2])==2):
File "<string>", line 1
01
^
SyntaxError: leading zeros in decimal integer literals are not permitted; use an 0o prefix for octal integers
Why am I getting this error, and how do I get rid of it?
though I haven't used '01' anywhere
Yes you have. The first element in dmy_split is '01'.
This is one of the many reasons why eval() is not recommended.
Why do you need eval() anyway? Just use int().
