在 csv 文件中搜索特定的 str
Search for specific str in a csv file
我必须创建一个猜谜游戏,每个用户都创建一个电影库,然后另一个人必须猜测电影名称。
我将电影保存到 csv 文件中。我正在尝试创建一个用户猜测的功能,如果在 csv 中找到电影名称,则打印“恭喜”,否则“再次猜测”。我让它读取文件,但它 return 再次猜测或恭喜文件中的每个字段。我怎么能只 return 一次呢?如果它在任何字段中打印恭喜,或者如果它不在任何字段中则再次猜测但只猜一次。我不想让它按特定行号搜索,因为它可以在任何行中找到。
这是我当前使用的函数,其中引用的 csv 文件是其他播放器的电影标题列表。
def guessingPlayer1v3(num_guesses):
for guess in range(0, num_guesses):
Guess=input("Movie title guess: ") #players guess
Guess=Guess.lower().strip() #guess to search for
with open('collection2.csv', 'r') as f_obj:
reader=csv.reader(f_obj, delimiter=',')
for row in reader:
for field in row:
if field == Guess:
print("Congrats, you guessed a title")
else:
print("Guess Again")
它是 returning:
Movie title guess: cat in the hat
Guess Again
Guess Again
Guess Again
Guess Again
Guess Again
Guess Again
Movie title guess: all dogs go to heaven
Guess Again
Guess Again
Guess Again
Congrats, you guessed a title
Guess Again
Guess Again
您可以尝试这样的操作:
import csv
listOfMovies = []
with open('collection2.csv', newline='') as f:
reader = list(csv.reader(f))
for line in reader:
listOfMovies.append(line[0])
def guessingPlayer1v3(num_guesses):
for guess in range(0, num_guesses):
Guess=input("Movie title guess: ").lower().strip()
if Guess in listOfMovies:
print("Congrats, you guessed a title")
break
else:
print("Guess Again")
有两个print
语句,第一个判断玩家输入是否正确,第二个显示每行 "Guess Again"
,删除 else
语句并添加 return
语句将避免这种情况,一旦名称存储在变量上,只需遍历所有行并进行比较...
for row in reader:
for field in row:
if field == Guess:
print("Congrats, you guessed a title")
return
print("Guess Again") # if movie is not in file
