以下是转换后的 Python 代码：

w = [0] * 100
p = [0] * 100
x = [0] * 100
x1 = [0] * 100
max_val = -1
total = 0

def knap8(n, m):
    global max_val, total, w, p, x, x1

    i = 1
    while True:
        while i <= n and total + w[i] <= m:
            total += w[i]
            sum_val += p[i]
            x[i] = 1
            i += 1

        if i == n + 1 and max_val < sum_val:
            max_val = sum_val
            i = n
            for j in range(1, n + 1):
                x[j] = xl[j]
        else:
            x1[i] = 0

        while bound(sum_val, total, i, m, w, p) <= max_val:
            while i > 0 and x[i] != 1:
                i -= 1
            if i == 0:
                return
            x[i] = 0
            total -= w[i]
            sum_val -= p[i]

        i += 1

def bound(sum_val, total, i, m, w, p):
    bound_val = sum_val
    j = i + 1
    while j <= n and total + w[j] <= m:
        bound_val += p[j]
        total += w[j]
        j += 1
    if j <= n:
        bound_val += (m - total) * p[j] / w[j]
    return bound_val

def main8():
    global max_val, total, w, p, x, x1

    n, m = map(int, input().split())
    for i in range(1, n + 1):
        w[i], p[i] = map(float, input().split())

    knap8(n, m)

    for i in range(1, n + 1):
        print(f"x{i} = {x[i]}")

    print(f"The max value is {max_val}")

if __name__ == '__main__':
    main8()

需要注意的是，原始的 C 语言代码存在一些语法错误，如 `total + w[i]< = m` 应该改为 `total + w[i] <= m`，因此在转换成 Python 代码时需要进行一些调整。同时，需要将函数的参数传递进去，以便在 Python 中使用。
