TypeError: decoding str is not supported

问题:

Im trying to make a attribute characteristic randomiser for my nephews board game and I'm trying to write the attributes to an external file so that he can use them later. when i am trying to write to the file it comes up with the error

speedE = str('Speed -', str(speed)) TypeError: decoding str is not supported 

my code is adding the calculated attribute to the name of the attribute. I.E. ('Strength - ', strengthE) my code is ...

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() 

im quite new to writing to external files and its not going too well aha. me and my nephew would really appreciate it if you could help, Thanks

回答1:

Not sure about what you expect str('Speed -', str(speed)) to do.

What you want is a string concat:

speedE2 = 'Speed -' + str(speed) # replace other lines also 

You can also use string formatting and not worry about type casts:

speedE2 = 'Speed -{}'.format(speed)
