在对 dataframe 数据框中某列进行时间戳转换，或其他变换时，出现 ValueError: cannot convert float NaN to integer 这是因为这列中存在空值，无法转换，所以首先找出空值所在的行，然后将其删除；即可。
Next, we will use np.array() function to convert the list of floats to integer.int_list = np.array(float_list).astype(int).tolist() print(int_list) # [1, 3, 5]In the astype() function, we specified that we wanted it to be converted to integers, and then we chained the to...

int(x, base=10) -> integer Convert a number or string to an integer, or return 0 if no arguments are given. If x is a number, return x.__int__(). For floating point numbers, this truncates towards zero. If x is not a number or if base is given, then x must be a string...

Example 2: Transform List Elements from String to Integer Using List Comprehension Alternatively to the map function shown in Example 1, we may also uselist comprehensionto convert character strings to integer. Example 2 explains how to achieve that based on our example list. Consider the Python ...
