ifisinstance(float_to_int,float): float_to_int ='%d'%sheet.cell(行,列).value 因为是端口所以转int,可根据实际情况选择 int 或 str。 转str类型用str()函数即可, 1 str(sheet.cell(行,列).value) 另,还可以用map函数 1 float_to_int = map(str, sheet.cell(行,列).value) str是指明需要的类...
Python报错:TypeError: sequence item 0: expected str instance, int found 报错原因: student_list = [1, 2, 3, 4, 5] 使用" ".join(student_list)时,student_list中的元素都为整数。 解决方法: 将student_list中的元素都变为str类型 list(map(str, student_list)) 关于map函数,跳转:https://www.cn...
TypeError: sequence item 0: expected str instance, float found To fix this, you need to convert the floats to strings before joining them: floats = [1.1,2.2,3.3]print(' '.join(map(str, floats))) This will output: 1.1 2.2 3.3
