Python Condition use karne ke tarike:

1. Condtion sysntax:
    a. single condtion syntax:
        if yourCondtion:
            body of if

    b. condition worng hone par default else part ka use:
        if yourCondtion:
            body of if
        else:
            body of else

    c. multiple condtion ka use:
        if yourCondtion:
            body of if
        elif yourCondtion:
            body of if
        .
        .
        .
        else:
                body of else

2. Condtion ka use karne ke liye hame operatores ka use karna hota hai.

Python conditons:

Note: a and b are two varabils jinka use yaha kiya gaya hai.

1. equals: a == b
2. not equal to: a != b
3. less then: a < b
4. less then or equal to: a <= b
5. greater then: a > b
6. greater then or equla: a >=  b
'''

name = input('Enter your name: ')

# agar koi name deta hai to hum condtion ka use karke name show karyenga other waise error message show karenge.
if bool(name) == True:
    print('Hi, ',name)
else:
    print('Pleas enter your name then press enter.')

# use multiple condtion
if name.isalpha() == True:
    print('Hi, ' + name + ' welcome back.')
elif name.isalnum() == True:
    print('You used alphabets and digit. It\'s not acceptable.')
else:
    print('\nSomething wrong try again.')

# 2 number ke sath condtions: also useing nested case
a = 10
b = 10
c = 20

if a > b:
    print('if a > b: true')
elif a >= b:
    print('if a >= b: true')
    # nested condtion
    if c > a:
        print('if c > a: true')
        # sub nested condtion
        if a >= b:
            print('in sub nested if a >= b: true')
else:
    print('No one right.')

# use multiple condtion in single line
if a >= b and c < a or b < c and a != b:
    print('if a >= b: condtion is right')

# pass keyword ka use:
if a >= b and c < a or b < c and a != b:
    pass
