main4() {int m,n,i,j,w[50],p[50],p1[50],[50],s,max; input(m,n); for(i=1,s=0;i<=n;i=i+1) {input(w[i],p[i]);p1[i]= p[i];s=s+w[i];} if(s<=m) {print("whole choose") ; return;} for(i=1;i<=n;i=i+1) {max = 1; for(j=2;j<=n;j=j+1) if (p1[j]/w[j]> pl[max]/w[max]) max =j; p1[max] = 0;b[i] = max;} for(i=1,s=0;s<m and i<=n;i=i+1) s=s+w[b[i]]; if(s<>m) w[b[i-1]]=m-(s-w[b[i-1]]); for(j=1;j<=i-1;j=j+1) print("choose",b[j],"weight",w[b[j]]);}转为python语言

以下是将给定的代码转换为Python语言的过程：

def main4():
    m, n = input()  # 假设 input() 函数能够读取用户输入的 m 和 n
    w, p, p1, b = [0] * 50, [0] * 50, [0] * 50, [0] * 50
    
    for i in range(1, n + 1):
        w[i], p[i] = input()  # 假设 input() 函数能够读取用户输入的 w 和 p
        p1[i] = p[i]
        
    s = sum(w)
    if s <= m:
        print("whole choose")
        return
    
    for i in range(1, n + 1):
        max_idx = 1
        for j in range(2, n + 1):
            if p1[j] / w[j] > p1[max_idx] / w[max_idx]:
                max_idx = j
        p1[max_idx] = 0
        b[i] = max_idx
    
    s = 0
    for i in range(1, n + 1):
        s += w[b[i]]
        if s >= m:
            break
    
    if s != m:
        w[b[i - 1]] = m - (s - w[b[i - 1]])
    
    for j in range(1, i):
        print("choose", b[j], "weight", w[b[j]])

需要注意的是，上面的代码中涉及到了输入（input）和输出（print）操作，这些操作的具体实现和形式会因为具体的应用场景而有所不同。
