In this article, we are going to convert DateTime string of the format ‘yyyy-mm-dd’ into DateTime using Python. 

yyyy-mm-dd stands for year-month-day .

We can convert string format to datetime by using the strptime[] function. We will use the  ‘%Y/%m/%d’  format to get the string to datetime.

Syntax:

datetime.datetime.strptime[input,format]

Parameter:

• input is the string datetime
• format is the format – ‘yyyy-mm-dd’
• datetime is the module

Example: Python program to convert string datetime format to datetime

Python3

import datetime

input = '2021/05/25'

format = '%Y/%m/%d'

datetime = datetime.datetime.strptime[input, format]

print[datetime.date[]]

Example 2: Convert a list of string DateTime to DateTime

Python3

import datetime

input = ['2021/05/25', '2020/05/25', '2019/02/15', '1999/02/4']

format = '%Y/%m/%d'

for i in input:

    print[datetime.datetime.strptime[i, format].date[]]

Output

2021-05-25
2020-05-25
2019-02-15
1999-02-04

In this article, we are going to convert the DateTime string into the %Y-%m-%d-%H:%M:%S format. For this  task strptime[] and strftime[] function is used.

strptime[] is used to convert the DateTime string to DateTime in the format of year-month-day hours minutes and seconds

Syntax:

datetime.strptime[my_date, “%d-%b-%Y-%H:%M:%S”]

strftime[] is used to convert DateTime into required timestamp format

Syntax:

datetime.strftime[“%Y-%m-%d-%H:%M:%S”]

Here,

• &Y means year
• %m  means month
• %d means day
• %H means hours
• %M means minutes
• %S means seconds.

First the take DateTime timestamp as a String. Then, convert it into DateTime using strptime[]. Now, convert into the necessary format of DateTime using strftime

Example 1: Python program to convert DateTime string into %Y-%m-%d-%H:%M:%S format

Python3

from datetime import datetime

my_date = "30-May-2020-15:59:02"

d = datetime.strptime[my_date, "%d-%b-%Y-%H:%M:%S"]

print[d.strftime["%Y-%m-%d-%H:%M:%S"]]

Output

'2020-05-30-15:59:02'

Example 2: Python program to convert DateTime string into %Y-%m-%d-%H:%M:%S format

Python3

from datetime import datetime

my_date = "30-May-2020-15:59:02"

d = datetime.strptime[my_date, "%d-%b-%Y-%H:%M:%S"]

print[d.strftime["%Y-%m-%d-%H:%M:%S"]]

my_date = "04-Jan-2021-02:45:12"

d = datetime.strptime[my_date, "%d-%b-%Y-%H:%M:%S"]

print[d.strftime["%Y-%m-%d-%H:%M:%S"]]

my_date = "23-May-2020-15:59:02"

d = datetime.strptime[my_date, "%d-%b-%Y-%H:%M:%S"]

print[d.strftime["%Y-%m-%d-%H:%M:%S"]]

Output

2020-05-30-15:59:02
2021-01-04-02:45:12
2020-05-23-15:59:02
