Python-ValueError:以10为底的int()的无效文字:''
发布于 2021-02-02 23:17:57
我正在创建一个读取文件的程序,如果文件的第一行不为空白,它将读取接下来的四行。在这些行上执行计算,然后读取下一行。如果该行不为空,则继续。但是,我收到此错误:
ValueError: invalid literal for int() with base 10: ''.
它正在读取第一行,但无法将其转换为整数。
我该怎么做才能解决此问题?
代码:
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())
