TCS Quick Shots

#tutorial #python #showdev #quickshots

For the last couple of days, I am observing the question pattern in TCS. I would like to share some tricks and tips to crack the question in less time.

I hereby declare that these shots are only helpful for some type of questions in the Exam.

As of now Quick Shots are available in only Python Programming Language.

Good to Know

### Quick Inputs
name = raw_input() # for Strings
number = int(input()) # for Integers

Yes or No Questions

def yes_or_no():
    reply = str(raw_input('(y/n):')).lower().strip()
    if reply[0] == 'y':
        return True
    if reply[0] == 'n':
        return False
    else:
        return None

isMember = yes_or_no()

if(isMember == None): 
    print("Invalid Input")

Accepting Values in Same line (with Spaces)

values = [int(x) for x in raw_input().split()]
print(values)

# input: 1 2 3 4
# output: [1, 2, 3, 4]

Accepting Values in Same line (with Commas)

values = [int(x) for x in raw_input().split(', ')]
print(values)

# input: 1, 2, 3, 4
# output: [1, 2, 3, 4]

Percentage Questions

# 85% of 2043.43

def percentage(part, whole):
    return (part * whole)/100

print(percentage(85,2043.43))

# output: 1736.9155

Invalid Input

INVALID INPUT
Note: Input and Output should be formatted as given for the example.
For any wrong value input display “INVALID INPUT”

def inv():
    print("INVALID INPUT")

inv() 

# This helps you in code reusability 
# avoid this if have one possibility

Float decimal value after a point

value = 3282.2548

print("%.f"%value) # 3282
print("%.1f"%value) # 3282.3
print("%.2f"%value) # 3282.25
