1 All numbers in Perl have the same internal format, only double-precision floating-point numbers (there is no integer value inside perl). 2 Perl allows the use of underscores to delimit longer integers, such as 612980400283768 and 612_980_400_283_768 are the same values. 3 non-decimal integers in Perl: Octal begins wi

I am very grateful to superor for taking his own time and providing the first Chinese video tutorial for the Chinese Perl community. It is a good tutorial in other languages. Compared with Perl, Perl is still relatively small. It is quite convenient to watch videos when getting started, just like watching movies. I have read almost every episode of superor. I hop

Comparison between Python and Perl (1) The initial purpose of designing a language determines the built-in functions of the language: Perl was initially created by Larry to format and process text, so there is a built-in regular expression. In python, a plural type
