以下是将该段代码转换为Python语言的代码:
```python
w = [0] * 100
p = [0] * 100
n, m = 0, 0
def knap5(m, i):
if i == 0:
return 0
max1 = knap5(m, i - 1)
if m >= w[i]:
max2 = knap5(m - w[i], i - 1) + p[i]
else:
max2 = 0
if max1 > max2:
return max1
else:
return max2
def main5():
global n, m, w, p
s = 0
m, n = input().split()
m, n = float(m), int(n)
for i in range(1, n + 1):
w[i], p[i] = input().split()
w[i], p[i] = float(w[i]), float(p[i])
s += w[i]
if s <= m:
print("whole choose")
return
print("max =", knap5(m, n))
main5()
```
注意,Python的语法和C语言有些不同,需要进行一些相应的调整。例如,Python中的数组从0开始索引,而C语言从1开始索引,因此需要将数组的定义和访问方式进行修改。此外,Python中需要使用`global`关键字声明全局变量。
float w[100],p[100],x1[100],x[100]; main6( ) {int m,n,s=0,i; input(m,n); for(i=l;i<=n;i=i+1) {input(w[i],p[i]); s=s+w[i];} if(s<=m) {print("whole choose"); return;} knap6(1); for(i=1;i<=n;i=i+1) print("x",i+1,"=",x[i]);} float max = 0,total= 0; knap6(int i) {int j; float sum =0; if(i=n+1) {for(j=1;j<=n;j=j+1) sum=sum+xl[j]*p[j]; if(sum > max) {max= sum; for(j=1;j<=n;j=j+1) x[j]=x1[j];} return; x1[i]=0; knap6(i+1); if (total+ w[i]<=m) {xl[i]=1; total= total+ w[i]; knap6(i+1); x1[i]=0; total = total- w[i]; } }转换成python语言的代码
以下是将上述代码转换为 Python 语言的代码:
```python
w = [0] * 100
p = [0] * 100
x1 = [0] * 100
x = [0] * 100
max_value = 0
total = 0
def input_data(m, n):
for i in range(1, n+1):
w[i], p[i] = map(float, input().split())
def knap6(i, m, n):
global max_value, total, x1, x
if i == n+1:
sum_value = 0
for j in range(1, n+1):
sum_value += x1[j] * p[j]
if sum_value > max_value:
max_value = sum_value
for j in range(1, n+1):
x[j] = x1[j]
return
x1[i] = 0
knap6(i+1, m, n)
if total + w[i] <= m:
x1[i] = 1
total += w[i]
knap6(i+1, m, n)
x1[i] = 0
total -= w[i]
def main6():
m, n = map(int, input().split())
s = 0
input_data(m, n)
for i in range(1, n+1):
s += w[i]
if s <= m:
print("whole choose")
return
knap6(1, m, n)
for i in range(1, n+1):
print("x" + str(i+1) + " = " + str(x[i]))
main6()
```
请注意,这只是简单的代码转换,有一些细节可能需要根据实际使用情况进行修改。
