python - Python数组跳过索引的问题

问题描述

我有一个在数组中跳过索引的问题，如下所示 -


    start = linesa.index("enum {\n")

    print(linesa)
    i = start
    while True:
        print(i)
        print(linesa[i])
        if "};\n" in linesa[i]:
            break
        print(linesa.pop(i))
        i += 1
    print(linesa)
    exit()

索引 39 是枚举{，而 40 是};但它跳过了 '\tID_CA_REQ_GAME_GUARD_CHECK = 0x0258\n'，索引

解决方案

使用 print(linesa[i]) 代替 print(linesa.pop(i))。如果要打印最后一个元素，请使用linesa[-1]

Pop 会减少linesa 的长度，并会导致循环内的尴尬行为。
