重復循環讀取文件，直到滿足條件

Question

我想逐行讀取文件。 這些行包含運算符和數字。 如果它是“+”我將添加后面的數字，它是“ - ”我將減去后面的數字。 這將保存在計數變量中。 然后，此計數變量將存儲在列表中。 我將繼續遍歷文件，直到找到重復的計數值。 我的想法是繼續循環，直到我找到重復（因此我的條件）。 但是當我到達文件的末尾時，我需要重新開始!! 因此，文件末尾的計數現在將從頭開始

while循環然后循環

def computeProblemOnePointFive(inputFileString):
    inputFile = open(inputFileString, "r")
    count = 0
    countsList=[]
    while len(countsList) == len(set(countsList)):
        for line in inputFile:
            if "+" in line:
                value = int(line.strip("+"))
                count = count + value
                countsList.append(count)
            if "-" in line:
                value = int(line.strip("-"))
                count = count - value
                countsList.append(count)
    return countsList[-1]

Answer 1

潛在的解決方案可能正在發展

inputFile = open(inputFileString, "r")

進入while循環

def computeProblemOnePointFive(inputFileString):
    # the line was here previously
    count = 0
    countsList=[]
    while len(countsList) == len(set(countsList)):
        inputFile = open(inputFileString, "r") #the line that was moved
        for line in inputFile:
            if "+" in line:
                value = int(line.strip("+"))
                count = count + value
                countsList.append(count)
            if "-" in line:
                value = int(line.strip("-"))
                count = count - value
                countsList.append(count)
    return countsList[-1]
