Expert Solution

def checkFormat(string):
length=len(string)
if(length!=19):
return False
if(string[4]!='@'):
return False
if(string[0:4].islower()==False):
return False
if(string[5:19]!="abcdefghij.edu"):
return False
return True

print(checkFormat("[email protected]"))
print(checkFormat("[email protected]"))
print(checkFormat("[email protected]"))
print(checkFormat("abcdtabcdefghij.edu"))
print(checkFormat("[email protected]"))
print(checkFormat("[email protected]"))
