一、數據預覽

數據預覽

二、方法分析

1. 建立實部.txt和虛部.txt兩個文件
2. 按行遍歷處理.xls數據
3. 判斷當前數據的類型是否是“float”，如果不是直接爲實數，將其存入到“實數.txt”文件中，將0存入到“虛數.txt”文件中（轉爲16進制）
4. 如果是“float”類型，則爲複數，需要提取實部與虛部，並分別保存到“實部.txt”文件和“虛部.txt”文件（轉化爲16進制）

（需要將負數加上256）

三、代碼示例

path = "C:\\Users\\LZN_GWI\\Desktop\\IFFT.xls"
path1 = "C:\\Users\\LZN_GWI\\Desktop\\"
file1 = open(path1 + "實部" + '.txt','a')
file2 = open(path1 + "虛部" + '.txt','a')
# file1 = open("C:\\Users\\LZN_GWI\\Desktop\\實部.txt",mode= 'a')
# file2 = open("C:\\Users\\LZN_GWI\\Desktop\\虛部.txt",mode= 'a')
exc_data = xlrd.open_workbook(path)
table = exc_data.sheets()[1]
rows = table.nrows
cols = table.ncols
print(rows,cols)
count = 0
for i in range(cols):
    exc_cols_data = table.col_values(i)
    for j in exc_cols_data:
        #print(type(j))
        if isinstance(j,float):
            if j != '':
