Day One

Basics

a = 10
b = 6
name = "Chad"

print(a+b)
print(id(a))

maths = 10
science =11
maths=89
print(id(maths))
print(maths)
print(id(science))

Swapping

# with temp variable
a = input()
b= input()

print(a)
print(b)

tmp = a
a= b
b= tmp
print(a)
print(b)

# without temp variable
a = input()
b= input()

print(a)
print(b)

# a,b = b,a or
a= a+b
b=a-b
a=a-b

print(a)
print(b)

Casting

a= True
b =False
c = 3.1234
d = "hello"
print(int(a))
print(int(b))
print(int(c))
# print(int(d)

a= True
b =False
c = 3.1234
d = "hello"
print(complex(a))
print(complex(b))
print(complex(c))
#print(complex(d))

print(bool(""))
print(bool(12))
print(bool(-12))
print(bool("hello"))

What is the Character

c = ord(input("Enter char:\n"))

if(c>=48 and c<=57):
    print("Number")
elif(c>=65 and c<=65+26):
    print("Caps")
elif(c>=97 and c<=97+26):
    print("No caps")
else:
    print("U r special")

Average

a = int(input())
b = int(input())
c=int(input())

tot = a+b+c
avg = a+b+c/3

print(tot)
print(avg)

Weekdays or Weekends

a = int(input())
b = int(input())
c= int(input())
d = int (input())
e = int(input())

if(a>b and a>c and a>d and a>e):
    print("A")
if(b>a and b>c and b>d and b>e):
    print("B")
if(c>a and c>b and c>d and c>e):
    print("C")
if(d>a and d>b and d>c and d>e):
    print("D")
if(e>a and e>b and e>c and e>d):
    print("E")

day = input("Enter day:\n")
if(day.lower()=="sunday" or day.lower()=="saturday"):
    print("weeknd")
else:
    print("weekday")

Passing criteria

m1 = int(input())
m2 = int(input())
m3 = int(input())
m4 = int(input())
m5 = int(input())
gender = input("Gender: ")
# M 60
# F 65

if(m1>=60 and m2>=60 and m3>=60 and m4>=60 and m5>=60 and gender == "M"):
    print("Pass")
if(m1>=65 and m2>=65 and m3>=65 and m4>=65 and m5>=65 and gender == "F"):
    print("Pass")
else:
    print("Fail")

avg = (m1 + m2+ m3 +m4 +m5)/500
perc = avg*100
print(perc)

If Elif

a = 12

test = [1,-1,0]
if (a>10):
    print("Greater than {}".format(a))
for ele in test:
    if(test==0):
        print("Zero")
    elif(tes>0):
        print("Greater than Zero")
    elif(tes<0):
        print("Less than ZZero")

String Operations

str1 = "python is not very good langauge"
print(str1.find("python"))
print(str1.find("hehe"))
s = "a","b","c"
m= '|'.join(s)
print(m)

print("{} is {}".format("hello","world"))

Jump

for i in range(1,6):
    if (i==3):
        continue
    print(i," ",6-i)

Tables

i =10
for i in range(1,i+1,2):
    print(i)
for i in range(1,20,-1):
    print(i)

for i in range (1,11):
    print(i," ",i*2," ",i*3," ",i*4," ",i*5," ",i*6," ",i*7," ",i*8," ",i*9," ",i*10)

for i in range(1,11):
    print(i*11," ",i*12," ",i*13," ",i*14," ",i*15," ",i*16," ",i*17," ",i*18," ",i*19," ",i*20)

String Operations

x= 10
y=10
print(y is x)
ar =[1,2,3]
print(1 in ar)

String slices

str1 = "supercalifragilisticexphihalidocious"
print(str1[:4])
print(str1[2:])
print(str1[3:5])
print(str1[::2])

String Loop

s = 'helloWorld'

for i in range(len(s)):
    if(s[i]=='h'):
        print(i)
for i in range(len(s)-1,0,-1):
    if(s[i]=='W'):
        print(i)

list =['a','e','i','o','u']
vow=0
cons=0
for i in s.lower():
    if i.lower() in list:
        vow=vow+1
    else:
        cons=cons+1
print("vow:",vow)
print("cons",cons)
