def task(w,n,c):
    if(w=='Monday'):
      person='James'
    elif(w=='Tuesday'):

或者用字典更简洁
def task(w,n,c):
    dict0={'Monday':'James','Tuesday':'John','Wednesday':'Robert','Thursday':'Michael','Friday':'William'}
    print('It is %s today, %s, you have to work, you must spray %d trees and you need %d dollars to buy liquid' % (w,dict0,n,c*n))

就是字符串操作
def task(w,n,c):
    dic = {'Monday':"James","Tuesday":"John","Wednesday":"Robert","Thursday":"Michael","Friday":"William"}
    try:
      return 'It is %s today, %s, you have to work, you must spray %d trees and you need %d dollars to buy liquid'%(w,dic,n,c*n)
    except KeyError:
      return "No one works on %s"%w

没有抄袭，只是发了两次，两次都是我发的，不过你们竟然能这么快恢复也是让我眼前一亮，不和你聊了，我去 ...

其实我想告诉你爬草榴的精髓不在于python，而在于如何翻墙。
