Typeerror: 'int' Object Does Not Support Item Assignment Error

sig_txt: [45 67 83 32767 101 90 50] idx_rr:[101] // index after 32767 sig: [45 67 83 101 90 50] // all the elements except 32767 Basically what happens is from the original array,

Solution 1:

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.

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.

Try this

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

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

Solution 2:

After the line idx__rr = i+1, you are changing the data type of idx_rr, which was list previously, to int.

Change the variable name of the list to get rid of the error.
