完整值未使用Python写入文件

首先尝试将numpy数组转换为列表：

y = function(x) #  Inside this function I am generating binary values and stored to y
################  y is in numpy.ndarray form
################  x is a sine wave
y_list = y.tolist()  # Convert to python list
# use the with context manager and you don't need to call .close() explicitly
with open('filename.txt',"w+") as f:
    f.write(str(y_list))  #we have to convert the numpy.ndarray to a list and then  to str(y_list) which will write the entire bits.
