在代码完成搜索列表后如何打印，但在列表中找不到单词，因此它回复错误？

茉莉花

我有一个 for 循环，所以它可以遍历整个列表，但是我如何输入 for 就像最后一行没有名为 Bob 的明星并说这是一个错误？

big_str = "0.998448,0.035746,-0.042707,352,6.18,14\n0.873265,0.031968,0.486196,358,2.07,15,ALPHERATZ\n0.512379,0.020508,0.858515,432,2.28,21,CAPH\n0.883455,0.044652,-0.466383,720,5.41,34\n0.963482,0.055705,0.261913,886,2.83,39,ALGENIB\n0.752989,0.044458,0.656529,905,5.71,41"

def getStarString(n):
  line_list = big_str.split("\n")
  for x in line_list:
    y = getStarName(x)
    if y == "None":
        continue
    else:
        if y == n:
            print(x)
        if y != n:
            continue
            if y != n:
                print("ERROR: No star called " + n + " could be found.")
def getStarName(name):
  names = list(name.split(","))
  for i in range(0, len(names)):
    if len(names) == 7:
        x = names[6]
        return x
    else:
        return "None"

getStarString("ALGENIB")
getStarString("BOB")

找到匹配项时跳出循环。如果消息结束而没有中断，则使用else:of 子句for打印消息。

def getStarString(n):
  line_list = big_str.split("\n")
  for x in line_list:
    y = getStarName(x)
    if y != "None" and y == n:
        print(x)
        break
  else:
    print("ERROR: No star called " + n + " could be found.")
