The text file is read into the numpy array with the help of the loadtxt() function. And then, the data is printed into the list using the print() function. from numpy import loadtxt #read text file into NumPy array data = loadtxt('example.txt', dtype='int') #printing the data ...
解决方案:使用文件对象的readinto()方法 示例 import os.path def read_into_buffer(filename): buf=bytearray(os.path.getsize(filename)) with open(filename,'rb') as f: f.readinto(buf) return buf #test case with open('sample.bin','wb') as f: f.write(b'helloworld') buf=read_into_bu...
①默认分隔符不同,pd.read_csv()的默认分隔符是逗号(,),而pd.read_table()默认的分隔符是制表符(\t),这也解释了为什么前者并没有设置sep,而后者在上述操作中却设置了sep = "," ②语义上的用途不同,read_cav()名字说明它是为CSV文件设计的,read_table()更通用,适用于“任意分隔符的表格data”,尤其是....
