ValueError：帶基數10：‘的int()文本無效我正在創建一個讀取文件的程序，如果文件的第一行不是空白，它將讀取接下來的四行。在這些行上執行計算，然后讀取下一行。如果該行不是空的，它將繼續。但是，我得到了這個錯誤：ValueError: invalid literal for int() with base 10: ''.它正在讀取第一行，但不能將其轉換為整數。我能做些什么來解決這個問題？守則：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())

將整數的字符串表示形式傳遞給 int將浮點數的字符串表示形式傳遞到 float將整數的字符串表示形式傳遞給 float通過浮子進入 int將整數傳遞給 float
