一 概念
1 Python replace() 方法把字符串中的 old（旧字符串） 替换成 new(新字符串)，如果指定第三个参数max，则替换不超过 max 次。
2 用法：str.replace(old, new[, max])
二 源码
import numpy as np sample_list = [23, 22, 24, 25] new_array = np.array(sample_list) # Displaying the array file = open("sample.txt", "w+") # Saving the array in a text file content = str(new_array).replace(']','') content = str(content).replace('[','') file.write(content) file.close() # Displaying the contents of the text file file = open("sample.txt", "r") content = file.read() print("Array contents in sample.txt: ", content) file.close()
