1、使用try进行异常发现,使用while检测文件末尾进行读取
file_to_read = raw_input("Enter file name of tests (empty string to end program):") try: infile = open(file_to_read, 'r') while file_to_read != " ": file_to_write = raw_input("Enter output file name (.csv will be appended to it):") file_to_write = file_to_write + ".csv" outfile = open(file_to_write, "w") readings = (infile.readline()) print readings while readings != 0: global count readings = int(readings) minimum = (infile.readline()) maximum = (infile.readline())
2、使用for遍历读取的每一行,进行一次性的读取和输入
result = list() with open('../test/parameter.txt') as f: for line in f.readlines(): temp = list() # 逐个遍历对应每一行元素,将之转为对应的数据 b = line.strip(",][").split(',') if(len(b) >= 5): b.pop() for a in b: a = a.replace('[','').replace(']','') temp.append(float(a)) result.append(temp) #print("中途打印的temp是",temp) #print("加入到result中的结果是",result)
以上就是python两种不同的文件流读写,希望对大家有所帮助。更多Python学习指路:
