TypeError: strptime() argument 1 must be str, not int

any idea on solving this?

[wavic]

In d = datetime.datetime.strptime(day, '%Y-%m-%d') ( line 53 ) the format for the date is set with zero padded months and deys. But the 'day' variable contains '2018-8-6'. Try to change it to '2018-08-06'. According to the docs.

However, I don't understand why it throws TypeError.

---

My bad. The error is pointing line 61. Change it to: d = datetime.datetime.strptime(f'{str(year)}-{str(month)}-{str(day)}', '%Y-%m-%d')

[j.crater]

That would be becuase first argument should be a string, not int, as is currently in OPs code (line 61).
Try with this as an argument:

"{}-{}-{}".format(year, month, day)

If you use Python 3.6+ you can also use f-strings instead of format method.

[buran]

OP wants to create a datetime.datetime object. Why complicate things with creating string and then convert it to datetime.datetime object?

import datetime
year = 2018
month = 8
day = 6

my_datetime = datetime.datetime(year=year, month=month, day=day)
print(my_datetime.strftime('%A'))

Output:
Monday
