如何像python一样去打印ascii文本

Question

how to print ascii-text in go language like python does like picture shown below

Using python

Using Golang

Answer 1

The problem is that your text contains backtick (`), which happen to be delimiter character for golang's raw string literal. This situation is comparable to your python code had your text contains 3 consecutive double-quotes, which is the delimiter being used in your python code.

I don't see any quick escape from this situation without modifying your ascii text, as we don't have other options for raw string delimiter in golang like we have in python. You may want to store your ascii text in a text file and read it from there :

import (
    ....
    ....
    "io/ioutil"
)

func banner() string {
    b, err := ioutil.ReadFile("ascii.txt")
    if err != nil {
        panic(err)
    }
    fmt.Println(string(b))
}

If you're ok with slight modification to the ascii text source, then you can temporarily use other character that isn't used anywhere else in the ascii text to represent backtick, and then do string replacement to put the actual backtick in place. Or, you can use fmt.Sprintf to supply the problematic backtick :

ascii := fmt.Sprintf(`....%c88b...`, '`')
fmt.Println(ascii)
// output:
// ....`88b...
