类型错误：不支持 - 的操作数类型：'str' 和 'int' [Python]

Question

为什么这个错误一直出现？ 我只是想创建一个表。 代码如下：

import datetime


q= datetime.date(2004,12,25)

e= datetime.date(2019,11,23) 

f= datetime.date(2019,11,26)

p= datetime.date(2004,12,13)

nam=[["attack on titan",10,"completed",p,q],["one punch man",10,"WATCHING",e,f]]

print("|         NAME           | SCORE |   STATUS   |  DATE STARTED  |    DATE ENDED   |") 

for KI in nam:
  print("|",KI[0]," "*22-len(KI[0]),"|"," ",KI[1]," ","|",KI[2]," "*(10-len(KI[2])),"|",""*2,KI[3], 
         " "*2,"|"," "*3,KI[4]," "*2,"|")

不要过多关注空间乘法。

错误：

|         NAME           | SCORE |   STATUS   |  DATE STARTED  |    DATE ENDED   |


Traceback (most recent call last):


    line 9, in <module>

    print("|",KI[0]," "*22-len(KI[0]),"|"," ",KI[1]," ","|",KI[2]," "*(10-len(KI[2])),"|"," "*2,KI[3]," "*2,"|"," "*3,KI[4]," "*2,"|")


TypeError: unsupported operand type(s) for -: 'str' and 'int'

Answer 1

错误发生在" "*22-len(KI[0]) 。
" "*22是一个由 22 个空格组成的字符串， len(KI[0])是一个整数。
正如TypeError告诉你的那样，从字符串中减去一个整数是没有意义的。
我猜你的意图是" "*(22-len(KI[0])) 。
