Answer:
Circumference of drum = 18.86 m
Given:
Diameter of drum = 6 m
Radius of drum = 3 m
Find:
Circumference of drum
Computation:
Circumference of drum is called single rotation
Circumference of drum = 2πr
Circumference of drum = 2[22/7][3]
Circumference of drum = 18.857
Circumference of drum = 18.86 m

Answer:
def check_password(pwd):
c=0
d=0
for i in pwd:
if (i>='a' and i<='z') or (i>='A' and i<='Z'):
c+=1
elif i>='0' and i<='9':
d+=1
c+=1
if len(pwd)==c and d>=2 and len(pwd)>=8:
print("valid password")
else:
print("Invalid password")
ps=input("Enter password for checking : ")
check_password(ps)
Explanation:
- Loop through the password and check if it contains any alphabet.
- Increment the counter if it contains any alphabet.
- If it contains a number, increment both c and d variables.
- Finally display the relevant message.
