我正在尝试为我的侄子棋盘游戏制作一个属性特征随机化器，并且我正在尝试将属性写入外部文件，以便他以后可以使用它们。当我尝试写入文件时出现错误
speedE = str('Speed -', str(speed))
TypeError: decoding str is not supported
我的代码将计算的属性添加到属性的名称中。IE ('Strength - ',strengthE) 我的代码是...
import random
char1 = open('Character1.txt', 'w')
strength = 10
strength += int(random.randint(1, 12) / random.randint(1,4))
speed = 10
speed += int(random.randint(1, 12) / random.randint(1,4))
speedE = str('Speed -', str(speed))
char1.write(speedE)
strengthE = str('Strength -', str(strength))
char1.write(strengthE)
print(char1)
char1.close()
char2 = open('Character2.txt', 'w')
strength2 = 10
strength2 += int(random.randint(1, 12) / random.randint(1,4))
speed2 = 10
speed += int(random.randint(1, 12) / random.randint(1,4))
speedE2 = str('Speed -', str(speed))
char2.write(speedE2)
strengthE2 = str('Strength -', str(strength))
char2.write(strengthE2)
print(char1)
char2.close()
我对写入外部文件很陌生，而且进展不太顺利啊哈。如果您能提供帮助，我和我的侄子将非常感激，谢谢
