Question

所以我昨天发布了这段代码的另一部分，但我遇到了另一个问题。我为RPG创建了一个字符生成器，我试图让程序将字符表函数的输出转换为.txt文件，但我认为发生的事情是该函数可能会为某些函数返回None值。统计数据（这是完全正常的），然后当我尝试写入.txt文件时，我得到一个错误。我完全难过了，非常感谢帮助！

# Character Sheet Function.
def char_shee():
    print "Name:", name
    print "Class:", character_class
    print "Class Powers:", class_power
    print "Alignment:", alignment
    print "Power:", pow, pow_mod()
    print "Intelligence:", iq, iq_mod()
    print "Agility:", agi, agi_mod()
    print "Constitution:", con, con_mod()
    print "Cynicism:", cyn, cyn_mod()
    print "Charisma:", cha, cha_mod()
    print "All Characters Start With 3 Hit Dice"

编辑：这是我得到的输出：

Answer 1

使用print写入sys.stdout，它不会返回值。

您希望char_shee返回字符表字符串以将其写入文件，您只需要构建该字符串。

为了便于构建字符串，请使用列表来收集字符串：

def char_shee():
    sheet = []
    sheet.append("Name: " + name)
    sheet.append("Class: " + character_class)
    # ... more appends ...

    # Return the string with newlines
    return '\n'.join(sheet)

Answer 2

你在这里忘了括号：

target.write(char_shee())
target.close()

并且@Martijn Pieters指出你应该从char_shee()返回值，而不是打印它们。

我如何编写这个主要打印到文件的函数？
