如何从 python 中的数组中删除引号

Question

How to remove quotation marks from array. I am using np.array

my code

 c1=np.array([w])
    print(c1)

I tried the replace but it didn't work

a=str(c1).replace("'",'')

my code reads data from a text file and edits it. Subsequently, I will store them in an array and count the combinations from them my full code

import sys
from itertools import combinations 
import numpy as np
import pandas as pd
import time
import re


    f = open('nacdata.txt', 'r')
    lines = f.readlines()
    
    for i in lines:
        if i[0] != '<' and i[0] != '>' and i[0] != '=':
            p = str(' '.join(i.split()))
            #print(p)
            
        else:
            w = i[3:]
            w = ', '.join(w.split())
            #print(w)
            time.sleep(1)
            y = i[2]
            c1=np.array([w])
            print(c1)

output

['1, 4, 7']
['2, 5, 8']
['3, 6, 9']
['1, 2, 3']
['4, 5, 6']
['7, 8, 9']
['10, 11, 12, 13, 14, 15, 16, 17, 18']
['-10, -11, -12, -13, -14, -15, -16, -17, -18']
['10, 11, 12, 13, 14, 15, 16, 17, 18']
['-10, -11, -12, -13, -14, -15, -16, -17, -18']
['19, 20, 21, 22, 23, 24, 25, 26, 27']
['-19, -20, -21, -22, -23, -24, -25, -26, -27']
['10, 19, 28']
['11, 20, 29']
['12, 21, 30']
['13, 22, 31']
['14, 23, 32']
['15, 24, 33']
['16, 25, 34']
['17, 26, 35']
['18, 27, 36']

Answer 1

You can try:

data = "['1, 4, 7']"

data = data.replace("'","")
print(data)
print(type(data))

list_data = data.replace("[","").replace("]","").split(", ")
print(list_data)

list_data = [int(d) for d in list_data]
print(list_data)

Output:

[1, 4, 7]
<class 'str'>
['1', '4', '7']
[1, 4, 7]

Answer 2

I think you are trying to convert the data from c1 into a list of integers? For this, you can do:

c1 = [int(i) for i in c1[0].replace(" ", "").split(",")]
