TypeError：“ int”对象不支持项目分配错误

问题描述

sig_txt：[45 67 83 32767 101 90 50]

idx_rr： [101] //在32767之后的索引

信号：[45 67 83 101 90 50] //所有除32767

基本上发生的是来自原始数组，除值等于 32767 的元素以外的所有元素>传递给 sig 数组。而 idx_rr 会在 32767 之后立即获取值。我已经写了同样的python。但是我遇到了这个错误：

Basically what happens is from the original array, all except the element whose value is equal to 32767 is passed to the sig array. And idx_rr gets the value immediate after 32767. I have written a python for the same. But I am getting this error:

。我可以在这方面寻求帮助吗？

when I am trying to plot the idx_rr value of sig. Can I get some help on this.

R_peak = False
j = 0
k = 0
idx_rr = []
sig = []

for i in range (len(sig_txt)):
    if (sig_txt[i] == 32767):
        idx_rr = i+1
        idx_rr[j] = np.array(sig_txt[i+1])
        sig = i+1
        sig[k] = np.array(sig_txt[i+1])
        k = k + 1
        j = j + 1
        print(idx_rr)
        R_peak = True
    else:
        if (R_peak == False):
            sig = i
            sig[k] = np.array(sig_txt[i])
            k = k + 1

        else:
            R_peak = False

plt.figure(figsize=(20,8))
plt.plot(sig)
plt.scatter([idx_rr], [sig[idx_rr]], c='g')
plt.show()

TypeError: 'int' object does not support item assignment

推荐答案

使用 idx_rr = i + 1 以前定义的列表成为 int ，因此没有索引 idx_rr [j] 为其分配值。 sig 变量也是如此。

With idx_rr = i+1 the formerly defined list becomes an int so there's no index idx_rr[j] to assign a value to. The same applies to the sig variable.

请注意，问题不在于声明，python允许您重新输入-将变量分配给新类型。问题是 idx_rr 的类型为 int ，并且您无法访问和索引 idx_rr [j ] 的 int 。

Note that the problem is not the declaration, python allows you to re-assign a variable to a new type. The problem is that idx_rr is of type int and you cannot access and index idx_rr[j] of an int.

尝试一下

R_peak = False
j = 0
k = 0
idx_rr = []
idx_rr_int = 0
sig = []
sig_int = 0
for i in range (len(sig_txt)):
    if (sig_txt[i] == 32767):
        idx_rr_int = i+1
        idx_rr[j] = np.array(sig_txt[i+1])
        sig_int = i+1
        sig[k] = np.array(sig_txt[i+1])
        k = k + 1
        j = j + 1
        print(idx_rr_int)
        R_peak = True
    else:
        if (R_peak == False):
            sig_int = i
            sig[k] = np.array(sig_txt[i])
            k = k + 1

        else:
            R_peak = False

plt.figure(figsize=(20,8))
plt.plot(sig)
plt.scatter([idx_rr], [sig[idx_rr]], c='g')
plt.show()
