app=Tk()
app.geometry("500x400")
app.title("Hancie e-Learning Studio")


def check():
    txt = text.get()
    timeResult=timevalidation(txt)
    if timeResult==True:
        messagebox.showinfo("Info","The time is valid")
    else:
        messagebox.showerror("Error","Invalid time")


text=Entry(app,font=("Times New Roman",16))
text.pack()

btn=Button(app,text="Check Time",font=("Times New Roman",16), command=check)

import re

# Function to validate Gender
def timevalidation(time):

    # Regex to check valid time
    regex=re.compile("(0[1-9]|1[0-2]):([0-5][0-9]) ((a|p)m|(A|P)M)")
    if re.fullmatch(regex, time):
        timeResult=True
    else:
        timeResult=False

    return timeResult
